Description
Verfahren zur Herstellung eines trocknenden fetten Öles aus Rizinusöl. Gegenstand der vorliegenden Erfindung ist eine weitere Ausbildung des im Haupt patent beanspruchten Verfahrens zur Her stellung eines trocknenden fetten Öls aus Rizinusöl.
Erfindungsgemäss wird als wasserabspal tender Katalysator eine Alkalibisulfat-Ver bindung verwendet.
Beispiel: Rizinusöl wird in einem Rührwerkhessel zusammen mit Natriumbisulfat unter höhe rem atmosphärischem Druck langsam erhitzt, wobei die Wasserabspaltung durch das als Katalysator wirkende Natriumbisulfat be wirkt wird. Das verdampfende abgespaltene Wasser wird in einem Kühler kondensiert und so aus dem Reaktionsgemisch entfernt. Nach weiterem Erhitzen und Abkühlen wird das Rühren beendet. Das Natriumbisulfat kann mit einer neuen Partie Rizinusöl so gleich unter Rühren nach obiger Vorschrift weiter benutzt werden. Zur katalytischen Wasserabspaltung kann an Stelle des Natriumbisulfates eine andere Alkalibisulfat-Verbindung verwendet wer den, wie Kaliumbisulfat etc.
Process for the production of a drying fatty oil from castor oil. The present invention is a further embodiment of the method claimed in the main patent for the manufacture of a drying fatty oil from castor oil.
According to the invention, an alkali metal bisulfate compound is used as the water-releasing catalyst.
Example: Castor oil is slowly heated in a stirrer tank together with sodium bisulphate under higher atmospheric pressure, the elimination of water being effected by the sodium bisulphate, which acts as a catalyst. The evaporating water that is split off is condensed in a cooler and thus removed from the reaction mixture. After further heating and cooling, the stirring is stopped. The sodium bisulfate can be used with a new batch of castor oil while stirring according to the above instructions. For the catalytic elimination of water, another alkali metal bisulfate compound can be used in place of sodium bisulfate, such as potassium bisulfate etc.
