Description
Verfahren zur Herstellung des Glyzerinesters der Polyricinolsäure. Es sind bis jetzt schon Verfahren be kannt geworden, welche die Herstellung von Estern kondensierter Oxysäuren gestatten. Doch alle die Angaben betonen, dass zur Ge winnung .dieser Ester hohe Temperaturen notwendig sind; so finden sich die Angaben von<B>180'</B> und auch 235 . Es zeigte sich jedoch, dass es möglich ist, diese Ester bei tiefen Temperaturen darzustellen, voraus gesetzt, dass man geeignete Katalysatoren anwendet. Als solche Katalysatoren kommen Sulfosäuren in Frage.
Die Bildung der Ester der kondensierten Säuren geht .dann sehr leicht vor sich.
Vorliegende Erfindung beruht nun auf dieser neuen Erkenntnis und betrifft ein Verfahren zur Herstellung des GlyZerin- esters der Polyrizinolsäure, das dadurch ge kennzeichnet ist, dass Rizinolsäure in Gegen wart eines Katalysators auf Temperaturen unter 180 C erhitzt wird und dass man das Kondensationsprodukt unter Zugabe von Rizinusöl bis zur vollkommenen Absätti- gung weiter erhitzt. Die Erhitzung der Rizinolsäure in Gegen wart eines Katalysators kann im Vakuum stattfinden.
Als Katalysator können zum Beispiel Sulfosäuren verwendet werden. Beispiel: 100 gr Rizinolsäure, mit der Säure- Zahl = 180 werden mit 0,5 gr Naphten- Sulfosäure gemischt und auf dem Wasser bade unter Vakuum 6 Stunden erhitzt; nach dieser Zeit ist die Säurezahl auf 100 ge sunken, das heisst es hat sieh Dirizinolsäure gebildet.
Erhitzt man weiter, so sinkt die Säurezahl auch weiter und erreicht bei ge nügend langem Erhitzen 66 und nach sehr langem Erhitzen 44. Es bildet sich Poly- rizinolsäure.
Setzt man dem Produkte .dann noch Rizinusöl zu und setzt das Erhitzen weiter fort, so tritt vollkommene Absättigung der sauren Gruppe ein, und man erhält ein dickes, viskoses 01, das seiner chemischen Zusammensetzung nach als Glyzerinester der Poly-Rizinolsäure anzusprechen ist.
Process for the preparation of the glycerol ester of polyricinoleic acid. Processes have been known up to now which allow the production of esters of condensed oxy acids. But all of the information emphasizes that high temperatures are necessary to obtain these esters; you can find the information from <B> 180 '</B> and also 235. However, it turned out that it is possible to prepare these esters at low temperatures, provided that suitable catalysts are used. Sulfonic acids are suitable as such catalysts.
The formation of the esters of the condensed acids takes place very easily.
The present invention is based on this new finding and relates to a process for the production of the glycerine ester of polyrizinoleic acid, which is characterized in that ricinoleic acid is heated to temperatures below 180 ° C. in the presence of a catalyst and that the condensation product is added with castor oil Continue heating until it is completely saturated. The ricinoleic acid can be heated in the presence of a catalyst in a vacuum.
Sulfonic acids, for example, can be used as the catalyst. Example: 100 grams of ricinoleic acid with an acid number = 180 are mixed with 0.5 grams of naphthene sulfonic acid and heated under vacuum for 6 hours; after this time the acid number has dropped to 100, which means that diricinoleic acid has been formed.
If the heating is continued, the acid number also drops further and reaches 66 with long enough heating and 44 after very long heating. Polyricinoleic acid is formed.
If castor oil is then added to the product and heating continues, the acidic group is completely saturated, and a thick, viscous oil is obtained, which, according to its chemical composition, can be described as a glycerol ester of polycinoleic acid.
