title: Transesterification/acetylation of long chain alcohols with alkyl acetate.
abstract: Gas chromatographic characterizations of fatty alcohols are generally carried out as the free alcohols, trimethyl silyl or acetyl derivatives. In this study, transesterification/acetylation of long chain fatty alcohols is simply carried out by dissolving the alcohol in ethyl/methyl acetate and passing through a micro-column packed with solid NaOH. Reaction times are slightly different for alcohols of different chain length. Rice bran alcohols of 24-34 carbon atom are successfully acetylated. Also, castor oil methyl ester can be interesterified but with longer reaction time.
