چکیده انگلیسی
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.
