Description

Verfahren zur Herstellung von trocknenden Ölen Ester höherer Oxyfettsäuren, z.B. Rizinusöl, können durch Erhitzen mit einem Überschuß von Glycerin evtl. unter Zusatz von Katalysatoren in den entsprechenden Mono-oder Diester bzw. in ein Gemisch von diesen übergeführt werden. Diese Glycerinester sind einer Weiterveresterung mit höheren gesättigten oder ungesättigten Fettsäuren bzw. Harzsäuren zugänglich.Process for the production of drying oils, esters of higher oxy fatty acids, e.g. castor oil, by heating with an excess of glycerine, possibly under Addition of catalysts in the corresponding mono- or diester or in a mixture be convicted of these. These glycerol esters are further esterified accessible with higher saturated or unsaturated fatty acids or resin acids.

Es wurde gefunden, daß unter geeigneten Bedingungen bereits während der Umesterung eine Abspaltung von Wasser aus dem Molekül der Ricinolsäure stattfindet, so daß Ester mehrfach ungesättigter Säuren entstehen. Man kann auch in der Weise arbeiten, daß die Wasserabspaltung erst nach beendigter Umesterung durch weiteres Erhitzen, gegebenenfalls in Anwesenheit geeigneter Katalysatoren, vor oder gleichzeitig mit der Einführung weiterer Säurereste zu Ende geführt wird. Die Menge des austretenden Wassers braucht nicht den aus, dem Hydroxylgehalt des Ausgangsstoffes berechneten, theoretisch möglichen Betrag zu .erreichen.It has been found that under suitable conditions already during the transesterification involves splitting off water from the ricinoleic acid molecule, so that esters of polyunsaturated acids are formed. One can also in that way work that the elimination of water only after the transesterification by further Heating, if appropriate in the presence of suitable catalysts, before or at the same time is brought to an end with the introduction of further acid residues. The amount of exiting Water does not need the value calculated from the hydroxyl content of the starting material, theoretically possible amount.

Die so erhaltenen Produkte zeigen trocknende Eigenschaften und geben Filme von vorzüglicher Wasser- und Alkalibeständigkeit. Sie sind daher in hohem Maße zur Herstellung von wasser- und sofiabeständigen Lacken, Rostschutzfärben, usw. geeignet.The products thus obtained show drying properties and give Films with excellent water and alkali resistance. They are therefore in high Dimensions for the production of water- and sofa-resistant paints, anti-rust paints, etc. suitable.

Beispiel i-46,6 kg Rizinusöl werden mit 9,2 kg Glycerin in Gegenwart von Zoo g Calciumglycerat unter beständigem Rühren auf 275° erhitzt. Nachdem 2,71 Wasser ausgetreten sind, wird dem noch heißen Reaktionsprodukt die theoretisch nötige Menge (84 kg) von Leinölfettsäuren zugesetzt und bis zur vollkommenen Veresterung weitererhitzt.Example i-46.6 kg of castor oil are present with 9.2 kg of glycerol von Zoo g calcium glycerate heated to 275 ° with constant stirring. After 2.71 Water have escaped, the still hot reaction product becomes the theoretically necessary Amount (84 kg) of linseed oil fatty acids added and until complete esterification further heated.

Beispiele 46,6kg Rizinusöl werden mit 9,2 kg Glycerin in Gegenwart von Zoo g Calciumglycerat unter beständigem Rühren auf 275° erhitzt. Nachdem 2,71 Wasser ausgetreten sind, wird dem noch heißen Reaktionsprodukt die theoretisch nötige Menge Kolophonium zugesetzt und bis zur vollkommenen Veresterung weitererhitzt.Examples 46.6 kg of castor oil are mixed with 9.2 kg of glycerol in the presence von Zoo g calcium glycerate heated to 275 ° with constant stirring. After 2.71 Water have escaped, the still hot reaction product becomes the theoretically necessary Amount of rosin added and further heated until complete esterification.

B,eis:piel3 46,6 kg Rizinusöl werden durch ein viertelstündiges Erhitzen auf 275° in Gegenwart von Zoo g Calciumglycerat mit 9,2 kg Glycerin umgeestert. Dem noch heißen Reaktionsprodukt werden dann 8q. kg Leinölfettsäure zugefügt und das Gemisch so lange auf 21o bis 23o° erhitzt, bis die Säurezahl nicht weiter sinkt. Dann werden 5010 Bleicherde zugesetzt und weiter auf 210 bis 23o° erhitzt, bis 2,71 Wasser ausgetreten sind.B, eis: piel3 46.6 kg of castor oil are obtained by heating for 15 minutes to 275 ° in the presence von Zoo g calcium glycerate with 9.2 kg glycerine interesterified. The still hot reaction product are then 8q. kg of linseed oil fatty acid added and the mixture heated to 21o to 23o ° until the acid number is not continues to decrease. Then 5010 fuller's earth are added and further to 210 to 23o ° heated until 2.71 water has escaped.
