De boratestere, der anvendes i den hydrauliske væske ifølge opfindelsen, er også kendte forbindelser, der f.eks. er beskrevet i U.S.A. patent nr. 3,080,412 og i de engelske patenter nr.The borate esters used in the hydraulic fluid of the invention are also known compounds which e.g. are described in U.S.A. U.S. Patent No. 3,080,412;

1,232,369 og 1,232,370. Boratestere i henhold til formel III kan fremstilles ved at esterificere ortoborsyre med monoethere af oxyalkylen- eller polyoxyalkylenglycoler. Esterificeringen kan gennemføres ved konventionelle esterificeringsmetoder, og esterificeringen kan gennemføres med tre mol glycolmonoether pr. mol ortoborsyre, med et eller to mol glycolmonoether efterfulgt af 5 1A3506 esterificering med henholdsvis to eller et mol af en derfra afvigende glycolmonoether eller under anvendelse af en tretrinsproces med et mol af hver enkelt af tre forskellige glycolmonoethe-re. Esterificeringen gennemføres fortrinsvis med et lille overskud, f.eks. et overskud på 10 #, af glycolmonoetheren (d.v.s. i et overskud i forhold til det særlige molforhold). Ved en simpel ettrinsesterificering af et mol ortoborsyre foretrækkes det f.eks. at anvende 3,3 mol af glycolmonoetheren.1,232,369 and 1,232,370. Borate esters of formula III can be prepared by esterifying orthoboric acid with mono ethers of oxyalkylene or polyoxyalkylene glycols. The esterification can be carried out by conventional esterification methods, and the esterification can be carried out with three moles of glycol monoether per liter. moles of orthoboric acid, with one or two moles of glycol monoether followed by esterification with two or one moles of a deviating glycol monoether, respectively, or using a three-step process with one mole of each of three different glycol monoethers. The esterification is preferably carried out with a small excess, e.g. an excess of 10 #, of the glycol monoether (i.e., in excess of the particular molar ratio). For example, by a simple one-step esterification of a mole of orthoboric acid, it is preferred. using 3.3 moles of the glycol monoether.

Boratestere i henhold til formel IV kan fremstilles på lignende måde ved esterificering af borsyre med en eller flere glycol-monoethere i de passende mængder. Esterificeringen kan gennemføres under anvendelse af konventionel teknik. På lignende måde kan boratestere med formel V fremstilles ved konventionelle es-terificeringsmetoder. Således esterificeres borsyre, fortrinsvis ortoborsyre, med to gange den molære kvantitet af en eller flere glycolmonoethere til dannelse af et mellemprodukt med formlen R60—(—R^O ) \ B1·'1 —OH.Borate esters of formula IV can be prepared similarly by esterification of boric acid with one or more glycol monoethers in the appropriate amounts. The esterification can be carried out using conventional techniques. Similarly, borate esters of formula V can be prepared by conventional esterification methods. Thus, boric acid, preferably orthoboric acid, is esterified by twice the molar quantity of one or more glycol monoethers to form an intermediate of formula R60 - (- R

R^O R^O )/R 2 O R 2

Mellemproduktet omsættes derpå med den relevante, organiske di-eller polyhydroxyforbindelse, hvoraf gruppen R' er afledet,The intermediate is then reacted with the relevant organic di or polyhydroxy compound from which the group R 'is derived,

Boratestrene med formel VI og VII kan også fremstilles ved konventionelle esterific eringsmetoder, under aivendelse af de hensigtsmæssige molære forhold mellem borsyre og di-hydroxy-for-bindelser.The borate esters of formulas VI and VII may also be prepared by conventional esterification methods, using the appropriate molar ratios of boric acid and dihydroxy compounds.

Efter fremstilling af boratestrene kan separering og rensning gennemføres på kendt måde.After preparation of the borate esters, separation and purification can be carried out in known manner.

Man kan f.eks. anvende en andel på fra 5 til 20 vægt-# boratester, f;eks. 10 vægt-#. Som et alternativ kan man også anvende en andel af boratester på mellem 40 og 60 vægt-#, f.eks.The proportion of the borate ester used in the hydraulic fluid according to the invention may be between 2 and 80% by weight, preferably between 2 and 60% by weight, and many different values for this proportion can be selected within this preferred range, makes a similar choice of the content of dicarboxylic acid ester. One can, for example. apply a proportion of from 5 to 20% by weight borate ester, e.g. 10% by weight. Alternatively, a proportion of borate ester of between 40 and 60% by weight, e.g.

45 eller 55 vægt-#.45 or 55% by weight.

Som angivet i det foregående kan den hydrauliske væske ifølge opfindelsen indeholde konventionelle additiver til hydrauliske væsker, herunder korrosionsinhibitorer, såsom aminer og derivater deraf. Det har nu vist sig, at visse aminer også er anvendelige i de hydrauliske væsker med henblik på opfyldelsen af et andet formål. Det kan især fremhæves, at disse aminer undertrykker tendensen til udfældning af borsyre under anvendelse af den hydrauliske væske, idet borsyren fremkommer ved hydrolyse i nærværelse af absorberet, atmosfærisk fugtighed.As stated above, the hydraulic fluid of the invention may contain conventional hydraulic fluid additives, including corrosion inhibitors such as amines and derivatives thereof. It has now been found that certain amines are also useful in the hydraulic fluids for the purpose of fulfilling another purpose. In particular, it may be emphasized that these amines suppress the tendency to precipitate boric acid using the hydraulic fluid, the boric acid being produced by hydrolysis in the presence of absorbed atmospheric moisture.

De aminer, der er særligt anvendelige til stabilisering af de hydrauliske væsker, d.v.s. til undertrykkelse af bundfældning af borsyre, er alifatiske aminer og visse aromatiske aminer. Ved en fo-retrukken udførelsesform for opfindelsen indeholder væsken i overensstemmelse dermed en alifatisk amin, 1 særdeleshed en primær eller sekundær alif atisk amin. Det foretrækkes især at anvendeThe amines which are particularly useful for stabilizing the hydraulic fluids, i.e. for suppressing boric acid precipitation are aliphatic amines and certain aromatic amines. According to a preferred embodiment of the invention, the liquid accordingly contains an aliphatic amine, in particular a primary or secondary aliphatic amine. It is particularly preferred to use

• K• K

en primær eller sekundær alifatisk amin, der indeholder mellem 4 og 12 carbonatomer, f.eks. n-butylamin, n-laurylamin eller n-actylamin. Som angivet i det foregående kan man ved en foretruk-ken udførelsesform anvende visse aromatiske aminer i stedet for de alifatiske aminer. Eksempler på de aromatiske aminer omfatter diphenylamin, phenylhydrazin, p-phenylendiamin og o-, m-, eller p-aminophenol.a primary or secondary aliphatic amine containing between 4 and 12 carbon atoms, e.g. n-butylamine, n-laurylamine or n-actylamine. As indicated above, in a preferred embodiment, certain aromatic amines may be used in place of the aliphatic amines. Examples of the aromatic amines include diphenylamine, phenylhydrazine, p-phenylenediamine and o-, m-, or p-aminophenol.

Amin-stabiliseringsmidleme kan anvendes i en mængde mellem 0,1 og 5 vægt-#, fortrinsvis i en mængde mellem 0,5 og 3 vægt-#, beregnet i forhold til den totale vægt af den hydrauliske væske.The amine stabilizers can be used in an amount between 0.1 and 5% by weight, preferably in an amount between 0.5 and 3% by weight, calculated in relation to the total weight of the hydraulic fluid.

Det vil forstås, at man i forbindelse med opfindelsen kan anvende blandinger af de boratestere, der har været beskrevet i det foregående. Desuden kan man anvende "blandede" estere, d.v.s. estere, der er afledt af 2 eller flere forskellige glycolmonoethere. Sådanne "blandede" estere vil indeholde 2 eller flere forskellige glycolmonoether-remanenser i hvert molekyle, og der er mulighed 10 143506 for, at der i større eller mindre grad kan finde en omesterifice-ring sted, d.v.s. overføring af glycolmonoetherremanenser fra et boratom til et andet, således at der under drift dannes forskellige boratestere. Den resulterende blanding af boratestere vil naturligvis ikke kunne skelnes fra blandinger, der er fremkommet ved blanding af de separate estere i de passende mængder, og anvendelsen af sådanne blandinger i hydrauliske væsker er således omfattet af den foreliggende opfindelse.It will be appreciated that mixtures of the borate esters described above can be used in connection with the invention. In addition, "mixed" esters may be used, i.e. esters derived from 2 or more different glycol monoethers. Such "mixed" esters will contain 2 or more different glycol monoether residues in each molecule, and there is a possibility that a more esterification may take place, i.e. transferring glycol monoether residues from one boron atom to another so that different borate esters are formed during operation. Of course, the resulting mixture of borate esters will not be distinguishable from mixtures obtained by mixing the separate esters in the appropriate amounts, and the use of such mixtures in hydraulic fluids is thus encompassed by the present invention.

Ved anvendelsen af den hydrauliske væske ifølge opfindelsen foreligger der et hydraulisk system, der indeholder den hydrauliske væske ifølge opfindelsen. Anvendelsen udgøres af en fremgangsmåde til krafttransmission, som omfatter, at man indfører den hydrauliske væske ifølge opfindelsen i et hydraulisk system, og at man transmitterer kraft ved at udsætte dette for tryk.In the use of the hydraulic fluid according to the invention, there is a hydraulic system containing the hydraulic fluid according to the invention.

After the formation of 35 ml of water, 2.2 moles of diethylene glycol-mono ethyl ether were added and the reflux was continued for 5 hours until an additional 36 ml of water was formed. Then, 2.2 moles of diethylene glycol mono-methyl ether was added and the reflux was continued for 6 hours until 36 ml of water was formed. After completion of the esterification, toluene and excess glycol ether were distilled off (7.5 mm Hg / 100 ° C) to prepare methyl diethylene glycol-ethyl diethylene glycol-methyl-triethylene glycol borate (yield 774 g, 91%), having a SAE equilibrium reflux boiling point of 327 ° C and a viscosity of 889 cSt at -40 ° C.

For at illustrere egenskaberne af den hydrauliske væske ifølge opfindelsen blev de i det foregående angivne blandinger 2 til 22 undersøgt under anvendelse af mange forskellige, standardiserede undersøgelsesmetoder. Resultaterne af disse forsøg viste, at blandingerne var anvendelige søm hydrauliske væsker, især i hydrauliske bremse- og koblingssystemer. F.eks. vil blandingerne 2, 3 og 4, der gør brug af de samme esterbestanddele i varierende andele, alle fuldstændigt tilfredsstille de i SAE J 1703 b specifikationen opstillede krav til hydrauliske væsker af høj kvalitet til hårde belastninger, og de vil også tilfredsstille de strenge korrosionskrav, som fremgår af Ford ESA-M6C-1001-A specifikationen. Der er også andre blandinger, som fuldstændigt tilfredsstiller SAE J 1703 b specifikationen, eller den let reviderede SAE J 1703 c specifikation, 17 143506 der indførtes i det tidsrum, i hvilket blandingerne blev undersøgt. F.eks. vil blanding 10, hvori carboxylatesterbestanddelen udelukkende består af estere i henhold til formel II, i fuldt mål tilfredsstille de i SAE J 1703 c specifikationen opstillede krav.In order to illustrate the properties of the hydraulic fluid according to the invention, the blends 2 to 22 mentioned above were investigated using many different standardized testing methods. The results of these experiments showed that the mixtures were useful nail hydraulic fluids, especially in hydraulic braking and clutch systems. Eg. mixtures 2, 3 and 4 using the same ester constituents in varying proportions will all completely satisfy the requirements of high quality hydraulic fluids for heavy loads specified in SAE J 1703b, and they will also satisfy the strict corrosion requirements, as shown in the Ford ESA-M6C-1001-A specification. There are also other mixtures which completely satisfy the SAE J 1703 b specification, or the slightly revised SAE J 1703 c specification, 17 143506, introduced during the period during which the mixtures were examined. Eg. mixture 10, wherein the carboxylate ester component consists exclusively of esters of formula II, will fully meet the requirements set out in SAE J 1703c specification.

Forsøget viste også, at egenskaberne af blandingerne ikke svarede til et simpelt kompromis mellem de ønskede egenskaber ved høj temperatur af boratesterbestanddelen og de ønskede egenskaber ved lav temperatur af carboxylatesterbestanddelen. Tværtimod viste de undersøgte blandinger, at egenskaberne ved både lave og høje temperaturer blev bibeholdt i en uventet stor udstrækning, hvorved ^ der i visse tilfælde forekommer en i det væsentlige fuldstændig bibeholdelse af ønskværdige egenskaber både ved høje og lave temperaturer. Det skal især fremhæves, at den hydrauliske væske i-følge opfindelsen havde gode egenskaber i forbindelse med kogepunkter, damplåstemperaturer og viskositet ved lave temperaturer.The test also showed that the properties of the mixtures did not correspond to a simple compromise between the desired high temperature properties of the borate ester component and the desired low temperature properties of the carboxylate ester component. On the contrary, the investigated mixtures showed that the properties at both low and high temperatures were maintained to an unexpectedly large extent, whereby in some cases a substantially complete retention of desirable properties occurs at both high and low temperatures. In particular, it should be emphasized that the hydraulic fluid according to the invention had good properties in connection with boiling points, vapor lock temperatures and low temperature viscosity.

Disse egenskaber vil yderligere ikke forringes i noget utilbørligt omfang, selv i nærværelse af væsentlige vandmængder. Under driftsperioden af en hydraulisk bremsevæske absorberes der fugtighed fra 1 atmosfæren, og dette forringer væskens egenskaber. Hvis egenskaberne forringes i for stor en udstrækning, bliver driftseffektiviteten af det hydrauliske system, hvori væsken er inkorporeret, reduceret alvorligt. Det er derfor yderst vigtigt, at egenskaberne af en hydraulisk bremsevæske ikke forringes utilbørligt meget i nær- 1 værelse af vand.Furthermore, these properties will not deteriorate to any undue extent, even in the presence of significant water volumes. During the operation period of a hydraulic brake fluid, moisture is absorbed from the atmosphere and this degrades the properties of the fluid. If the properties are deteriorated to a great extent, the operating efficiency of the hydraulic system in which the fluid is incorporated is seriously reduced. It is therefore of utmost importance that the properties of a hydraulic brake fluid are not unduly degraded in the near room of water.

Viskositetsegenskabeme ved lav temperatur af den hydrauliske væske ifølge opfindelsen blev undersøgt ved bestemmelse af viskositeten ved -r40° C i overensstemmelse med den fremgangsmåde, der er beskrevet i SAE J 1703 specifikationen, hvorved viskositeten bestemmes i forbindelse med tørre prøver af de undersøgte væsker, og også 1 forbindelse med prøver, til hvilke der var tilsat kendte mængder vand. Resultaterne er angivet i den følgende tabel 1.The low temperature viscosity properties of the hydraulic fluid according to the invention were tested by determining the viscosity at -r40 ° C according to the method described in SAE J 1703 specification, whereby the viscosity is determined in connection with dry samples of the fluids tested and also 1 compound with samples to which known amounts of water were added. The results are given in the following Table 1.

Kogepunktet af de undersøgte væsker blev bestemt i henhold til den fremgangsmåde, der er angivet i SAE J 1703 specifikationen, idet kogepunktet bestemmes i forbindelse med tørre prøver af de undersøgte væsker og desuden i forbindelse med dobbeltprøver af væsken efter, at den er blevet udsat for en D.O.T. fugtighedsprø- 18 143506 ve i henhold til den fremgangsmåde, der er beskrevet i FM VS S 116 specifikationen. Pugtighedsprøven bliver i store træk gennemført ved at indeslutte en prøve af forsøgsvæsken i hver sin af to ekssikatorer og en prøve af en standardiseret referencevæske i hver sin af to yderligere ekssikatorer, hvorved <fer findes en vandig opslemning af ammoniumsulfat i hver ekssikator, hvilket tilvejebringer en atmosfære med 80 % relativ fugtighed* Prøverne holdes i ekssikatoren, indtil referencevæsken absorberer 3,5 vægt-# vand. De opnåede resultater angives i den følgende tabel 2.The boiling point of the tested fluids was determined according to the procedure set out in SAE J 1703 specification, the boiling point being determined in connection with dry samples of the tested fluids and, in addition, in duplicate samples of the liquid after being exposed to it. and DOT humidity tests according to the procedure described in the FM VS S 116 specification. The moisture test is broadly performed by enclosing a sample of the test liquid in each of two desiccators and a sample of a standard reference liquid in each of two additional desiccators, thereby providing an aqueous slurry of ammonium sulfate in each desiccator, providing a atmosphere with 80% relative humidity * The samples are kept in the desiccator until the reference liquid absorbs 3.5% by weight water. The results obtained are given in the following Table 2.

Damplåstemperaturerne af de undersøgte væsker blev bestemt under anvendelse af et apparat, der omfattede en i det væsentlige kugleformet glaspære med et hult, volumetrisk kalibreret, cylindrisk fremspring, der strækker sig vertikalt fra toppen af pæren, hvorved fremspringet er forseglet ved sin øvre ende. Et glasrør strækker sig lateralt fra bunden af pæren og strækker sig yderligere vertikalt langs pæren, før det afsluttes i en tragt. Pæren er fuldstændigt fyldt med forsøgsvæsken via tragten og glasrøret, således at der ikke forbliver nogen luftbobler i pæren. Pæren ned-dykkes derpå fuldstændigt i et varmebad, der er fyldt med en gennemsigtig væske, hvorigennem man kan iagttage den kalibrerede del af apparatet, og badets temperatur forøges gradvist. Når der forekommer dampdannelse, vil denne damp akkumuleres i den kalibrerede del af apparatet, og den temperatur, ved hvilken forud udvalgte mængder af damp akkumuleres, kan bestemmes. Den følgende tabel 3 viser de resultater, der opnås ved dette forsøg med tørre prøver af forsøgsvæske og desuden med en våd prøve af forsøgsvæske, der er fremkommet ved blanding af dobbeltprøver af den forsøgsvæske, der er blevet anvendt ved kogepunktsbestemmelserne efter D.O.T. fugtighedsprøveme.The vapor deposition temperatures of the liquids examined were determined using an apparatus comprising a substantially spherical glass bulb with a hollow, volumetrically calibrated cylindrical projection extending vertically from the top of the bulb, the projection being sealed at its upper end. A glass tube extends laterally from the bottom of the bulb and extends further vertically along the bulb before terminating in a funnel. The bulb is completely filled with the test liquid via the funnel and the glass tube so that no air bubbles remain in the bulb. The bulb is then completely immersed in a hot bath filled with a transparent liquid through which the calibrated portion of the apparatus can be observed and the temperature of the bath gradually increased. When vaporization occurs, this vapor will accumulate in the calibrated portion of the apparatus and the temperature at which pre-selected amounts of vapor accumulate can be determined. The following Table 3 shows the results obtained in this test with dry samples of test liquid and in addition with a wet sample of test liquid obtained by mixing double samples of the test liquid used in the boiling point determinations according to D.O.T. fugtighedsprøveme.

Gummikvældningsegenskaberne af fors øgs væskerne blev også bestemt i overensstemmelse med den fremgangsmåde, der er beskrevet i SAE J 1703 specifikationen. De opnåede resultater er anført i den følgende tabel 4.The rubber swelling properties of the test liquids were also determined according to the procedure described in SAE J 1703 specification. The results obtained are listed in the following Table 4.

De resultater, der er angivet i tabel 1, viser, at den hydrauliske væske ifølge opfindelsen har samme høje kvalitetsstandard hvad angår viskositetsegenskaber ved lav temperatur i nærværelse af vand som de kendte hydrauliske væsker på basis af carboxylate strene i 143506 henhold til de i det foregående angivne formler I og II uden tilsætning af boratestrene. Hydrauliske væsker på basis af borat-estrene, uden nærværelse af carboxylatestere, vides omvendt at have relativt ringe viskositetsegenskaber ved lav temperatur i nærværelse af vand.The results set forth in Table 1 show that the hydraulic fluid of the invention has the same high quality standard of low temperature viscosity properties in the presence of water as the known carboxylated hydraulic fluids of 143506 according to the foregoing formulas I and II without the addition of the borate esters. Conversely, hydraulic fluids based on the borate esters, without the presence of carboxylate esters, are known to have relatively poor viscosity properties at low temperature in the presence of water.

På lignende måde viser de resultater, der er angivet i tabellerne ; ; 2 og 3, at egenskaberne af den hydrauliske væske ifølge opfindelsen ved høj temperatur er sammenlignelige med egenskaberne ved høj temperatur af væsker på basis af boratestere, uden at der er carboxylatestere tilstede, hvorimod væsker på basis af carboxylatestere uden boratestere vides at have relativt ringe egenskaber ved høj temperatur.Similarly, the results presented in the tables show; ; 2 and 3, that the properties of the hydraulic fluid according to the invention at high temperature are comparable to the high temperature properties of liquids based on borate esters without carboxylate esters present, whereas liquids based on carboxylate esters without borate esters are known to have relatively poor properties. at high temperature.

Resultaterne i forbindelse med gummikvældningsegenskabeme, der er sammenstillet i tabel 4, viser, at den hydrauliske væske ifølge opfindelsen kan blandes, således at der er overensstemmelse med de sædvanligt accepterede standarder, der kræves ved sådanne spe- ' cifikationer som SAE J 1703 specifikationen.The results of the rubber swelling properties compiled in Table 4 show that the hydraulic fluid of the invention can be mixed so as to conform to the generally accepted standards required by such specifications as the SAE J 1703 specification.
