With Brucea javanica oil as raw material, anhydrous ethanol as reactant and solvent, the ethyl esterification of Brucea javanica oil was studied. The optimal conditions of the ethyl esterification of Brucea javanica oil were obtained by single factor experiment and orthogonal experiment as follows: with sodium methoxide as catalyst, catalyst dosage 0.6% (based on the mass of Brucea javanica oil), molar ratio of anhydrous ethanol to Brucea javanica oil 6∶?1, reaction temperature 75?℃ and reaction time 2 h. Under these conditions, the yield of fatty acid ethyl ester of Brucea javanica oil was 92.38%. |
