In this article,unsaturated acid esterification(fatty acid ethyl ester)is prepared with tea oil used as material,ethyl alcohol as solvent,and alkaline as catalyst. By single factor test and orthogonal test,the following optimum processing parameters are obtained:reactant mol ratio(absolute alcohol/tea oil)6∶1,concentration of alkaline catalyst 0.6%,reaction time 2.5 h,and reaction temperature 75℃. The yield of ethyl is 93.4%.
