TL;DR: In this article, the authors studied the performance of kusum oil and the mixed fatty acids thereof from several solvents at various temperatures (+10° C to −60° C) and found that petroleum ether is comparable in efficiency to methanol and superior to both acetone and ethanol in respect of separation of the saturated and unsaturated components of the fatty acid mixture.
Abstract: The crystallizations of the kusum oil and the mixed fatty acids thereof were studied from several solvents at various temperatures (+10° C to −60° C). The results indicate in general that in the range of temperatures studied, petroleum ether as a single solvent is comparable in efficiency to methanol and superior to both acetone and ethanol in respect of separation of the saturated and unsaturated components of the fatty acid mixture. The saturated and unsaturated fractions of the oil also are better separated by petroleum ether than acetone. Further, oleic acid essentially free from linoleic acid is obtainable by a preliminary crystallization of the fatty acid mixture from petroleum ether at ca. −12° C, followed by two additional crystallizations from acetone at ca. −55° C. Kristallisation des Fettes und der Fettsauren von Schleichera trijuga Samen aus Losungsmitteln Die Kristallisation des Kusumols und seiner Gesamtfettsauren aus verschiedenen Losungsmitteln bei unterschiedlichen Temperaturen (+10° bis −60° C) wurde untersucht. Es zeigte sich, das zur Trennung der gesattigten von den ungesattigten Fettsauren Petrolather als Losungsmittel ebenso wirksam war wie Methanol und sogar wirksamer als Aceton und Athanol. Ferner lassen sich die gesattigten und ungesattigten Anteile des Oles mit Petrolather besser trennen als mit Aceton. Durch Vorkristallisation der Gesamtfettsauren aus Petrolather bei ca. −12° C und zwei weitere Kristallisationen aus Aceton bei ca. −55° C erhalt man Olsaure, die im wesentlichen frei von Linolsaure ist.
