Abstract
Description
Bekanntlich werden alkalische Peroxidbleichbäder, wie sie zum Bleichen von Cellulose dienen, gegen allzu rasche Zersetzung des Bades durch Zugabe von Stabilisatoren geschützt. Außerdem enthalten die Bleichflotten noch Netzmittel anionischer oder nichtionischer Art wie z.B. Alkansulfonate oder Alkylbenzolsulfonate oder Anlagerungsprodukte von Ethylen- oder Propylenoxid an Verbindungen mit aktivem Wasserstoff, wie z.B. Alkohole oder Phenole. Diese Netzmittel sollen eine gleichmäßige und schnelle Benetzung der Ware gewährleisten. Bei schnell laufenden Apparaten mit Haspelkufen oder Jigger ist aber beim Einsatz anionischer und nichtionischer Netzmittel mit Schaumbildung zu rechnen, was zu erheblichen praktischen Schwierigkeiten führen kann. Um dies zu vermeiden, setzt man den Bleichflotten Entschäumer zu, die natürlich alkalistabil, temperaturstabil und peroxidstabil sein müssen. Bleichrezepturen enthalten somit immer eine Fülle von Einzelkomponenten und es stellt sich die Aufgabe, Substanzen zu finden, die alle genannten Forderungen gleichzeitig erfüllen.It is known that alkaline peroxide bleaching baths, such as those used for bleaching cellulose, are protected against the bath being decomposed too quickly by the addition of stabilizers. The bleaching liquors also contain wetting agents of an anionic or nonionic type, such as Alkanesulfonates or alkylbenzenesulfonates or adducts of ethylene or propylene oxide with active hydrogen compounds, such as e.g. Alcohols or phenols. These wetting agents are intended to ensure uniform and quick wetting of the goods. In the case of fast-running apparatuses with reel runners or jiggers, however, foam formation can be expected when using anionic and nonionic wetting agents, which can lead to considerable practical difficulties. To avoid this, anti-foaming agents are added to the bleaching liquors, which of course have to be alkali-stable, temperature-stable and peroxide-stable. Bleaching formulations always contain an abundance of individual components and the task is to find substances that meet all of the above requirements at the same time.
Es wurde nun gefunden, daß sich Alkylpolyglykol-tert.-bu- tyläther als Stabilisatoren in alkalischen Peroxidbleichbädern eignen und daß diese Verbindungen gleichzeitig als schaumarmes bis schaumfreies Netzmittel wirken.It has now been found that alkyl polyglycol-tert-bu - tyläther suitable as stabilizers in alkaline Peroxidbleichbädern and that these compounds as foaming act simultaneously to foam-free wetting agents.
Gegenstand der Erfindung ist daher die Verwendung von Verbindungen der allgemeinen Formel
Die Verbindungen der obigen Formel sind aus der DE-OS 25 56 499 bekannt. Bevorzugt sind solche Verbindungen, bei denen R C8-C18-Alkyl, C8-C18-Alkenyl und C8-C18-Alkylaryl bedeutet. Die Alkyl- bzw. Alkenylgruppen können geradkettig oder verzweigt sein. Als Aryl ist die Phenylgruppe bevorzugt.The compounds of the above formula are known from DE - OS 25 56 499. Preferred compounds are those in which RC 8 -C 18 alkyl, C 8 -C 18 alkenyl and C 8 -C 18 alkylaryl. The alkyl or alkenyl groups can be straight-chain or branched. The phenyl group is preferred as the aryl.
Das Bleichbad hat die übliche Zusammensetzung und enthält als bleichendes Agens Wasserstoffperoxid oder Verbindungen die in wässriger Lösung Wasserstoffperoxid bilden. Der pH-Wert der Bleichbehälter wird mit Alkali wie Natriumhydroxid oder Natriumcarbonat auf 9 bis 14, vorzugsweise 11 bis 13 eingestellt. Zu diesem Bleichbad gibt man 0,5 bis 5, vorzugsweise 0,5 bis 3 g/l des Hilfsmittels der obigen Formel. Beim Bleichen in kurzer Flotte, wo die Konzentration an Wasserstoffperoxid etwa 10 bis 20 mal höher ist als bei der Bleiche in langer Flotte verwendet man höhere Mengen des Hilfsmittels bis ca. 20 g/l. Die Verbindungen der obigen Formel können einzeln oder in Mischung miteinander, wasserfrei oder in Form wässriger Zubereitungen eingesetzt werden. Selbstverständlich ist es auch möglich, zusätzlich herkömmliche Stabilisier-, Netz- und Antischaummittel mitzuverwenden.The bleaching bath has the usual composition and contains hydrogen peroxide or compounds which form hydrogen peroxide in aqueous solution as the bleaching agent. The pH value of the bleaching vessel is adjusted with an alkali such as sodium hydroxide or sodium carbonate to 9 to 14, preferably 11 to. 13 0.5 to 5, preferably 0.5 to 3 g / l of the auxiliary of the above formula are added to this bleaching bath. For bleaching in a short liquor, where the concentration of hydrogen peroxide is about 10 to 20 times higher than for bleaching in a long liquor, higher amounts of the auxiliary are used up to about 20 g / l. The compounds of the above formula can be used individually or in a mixture with one another, anhydrous or in the form of aqueous preparations. Of course, it is also possible to use conventional stabilizing, wetting and anti-foaming agents.
Die Schaumfreiheit der Alkylpolyglykol-tert.-butyläther ist besonders dann gegeben, wenn die Temperatur des Bleichbades über dem Trübungspunkt dieser Hilfsmittel liegt, so daß dieses Hilfsmittel ganz oder teilweise ausgetrübt ist. Verwendet man die Verbindungen der obigen Formel unterhalb ihres Trübungspunkts, so erreicht man zwar eine gewisse Schaumarmut, aber keine vollständige Schaumfreiheit. Dementsprechend liegt die bevorzugte Temepratur zum Bleichen bei ca. 60 bis 100°C. Der Trübungspunkt der oben beschrienen Hilfsmittel kann durch Zugabe von oxethylierten Alkylphenolen variiert, z.B. heraufgesetzt werden. Der Anteil dieser oxethylierten Alkylphenole, wobei Nonylphenol mit 5 bis 50 Ethylenoxideinheiten bevorzugt ist, kann bis zu ca. 95 Gew. % betragen bezogen auf die Summe von Alkylpolyglykol-tert.-butyläther und Alkylphenol-oxalkylat.The freedom from foam of the alkyl polyglycol tert-butyl ether is particularly given when the temperature of the bleaching bath is above the cloud point of these auxiliaries, so that this auxiliary is wholly or partially clouded. If the compounds of the above formula are used below their cloud point, a certain amount of foam is achieved, but not completely free of foam. Accordingly, the preferred temperature for bleaching is about 60 to 100 ° C. The cloud point described above Aid can be varied, for example increased, by adding ethoxylated alkylphenols. The proportion of these ethoxylated alkylphenols, with nonylphenol having 5 to 50 ethylene oxide units being preferred, can be up to approximately 95% by weight, based on the sum of alkylpolyglycol tert-butyl ether and alkylphenol oxyalkylate.
In den folgenden , die Erfindung erläuternden Beispielen wird*der Peroxidabbau bis zu einer Dauer von 2 Stunden verfolgt. Von praktischer Bedeutung sind Bleichzeiten zwischen 10 und 30 Minuten. Das zu bleichende Cellulosematerial kann aus Baumwolle, Leinen, Nessel, Jute, Regeneratcellulose sowie aus Mischungen von Cellulose mit Synthesefasern bestehen. Nach dem Bleichvorgang wird das Bleichgut gespült und getrocknet. Anschließend werden Weißgrad, Saugfähigkeit und Polymerisationsgrad als Wirksamkeitskriterien bestimmt. Die Stabilisatorwirkung der Alkylpolyglykol-tert.-butyläther wird durch titrimetrische Bestimmung des Peroxidgehaltes währed des Bleichvorganges erfaßt. Das Schaumverhalten der Bleichflotten wird bei 80°C bestimmt. Um eine möglichst starke Flottenbewegung zu erzeugen, wird in Labortests die Bleichflotte im Kreislauf durch ein senkrechtes Rohr gepumpt.Nach Austritt aus dem Rohr fällt der Flottenstrahl 30 cm auf die in einem kalibrierten heizbaren Gefäß sich befindende Flotte, wobei die Höhe der nach einer Minute gebildeten Schaummenge gemessen und der zeitliche Abbau des Schaumes verfolgt wird. * unter anderemIn the following, the invention provides illustrative examples of peroxide decomposition is monitored up to a period of 2 hours *. Bleaching times between 10 and 30 minutes are of practical importance. The cellulose material to be bleached can consist of cotton, linen, nettle, jute, regenerated cellulose and mixtures of cellulose with synthetic fibers. After the bleaching process, the bleach is washed and dried. The degree of whiteness, absorbency and degree of polymerization are then determined as effectiveness criteria. The stabilizing effect of the alkyl polyglycol tert-butyl ether is determined by titrimetric determination of the peroxide content during the bleaching process. The foaming behavior of the bleaching liquors is determined at 80 ° C. In order to generate the strongest possible movement of the liquor, the bleaching liquor is pumped in a circuit through a vertical pipe, and after exiting the pipe, the liquor jet falls 30 cm onto the liquor in a calibrated, heated vessel, the height of which is formed after one minute The amount of foam measured and the temporal degradation of the foam is followed. * among others
