Preparation of phytol fatty acid ester

Abstract

Abstract PURPOSE: To prepare the title compound useful as a component of essential oil of jasmine, easily, in high purity, by reacting a fatty acid with a thionyl halide in DMF, and then reacting the reaction product with phytol. CONSTITUTION: A fatty acid (pref. 10-20C saturated or unsaturated fatty acid, e.g. palmitic acid, stearic acid, etc.) is dissolved in DMF, and made to react with a thionyl halide. Without separating the reaction mixture, it is further reacted with phytol to obtain the objective compound. Since the objective compound has low solubility to DMF, the reaction mixture can be easily separated into two phases, i.e. a DMF layer containing unreacted fatty acid, etc., and a layer containing the objective compound. EFFECT: Since the difficult separation process of the unreacted fatty acid from the objective compound is not necessary, the process enables the production of the compound in large quantity.
