Solubilities of fatty acids and derivatives in acetone

Abstract

Summary An improved “synthetic” method of determining solubilities has been described which combines simplicity with accuracy. Saturated fatty acids with even numbers of carbons from C 6 to C 18 and oleic, linoleic, and linolenic acids, their methyl esters, their simple triglycerides and their corresponding alcohols have been prepared in purified form. The solubilities in acetone of their most stable forms have been determined from ordinary room temperatures down to about −70°C. or to temperatures where they are only slightly soluble. The precipitation of unstable polymorphs from solutions was observed in the case of palmityl alcohol.
