Preparation
By esterification of ethanol with stearic acid.
General Description
Ethyl stearate is a fatty acid ethyl ester (FAEE) is commonly found in vegetable oils.
Purification Methods
The solid portion is separated from the partially solid starting material, then crystallised twice from EtOH, dried by azeotropic distillation with *benzene, and fractionally distilled through a spinning-band column at low pressure [Welsh Trans Faraday Soc 55 52 1959]. [Beilstein 2 IV 1218.]
