| Abstract: | In this experiment , ascorbic acid and palmitate etbylester were used as reactants,and H2SO4 as catalyst to synthesize L-ascorbic palmitate by ester exchange method . The influence on yield by the molar ratio of ascorbic acid to palmitate ethylester, consistence of catalyst, reaction temperature , reaction time, et al. were studied. After optimization of experimental parameters , the yield was 75%. The product satisfied the requirement of criterion of GB 16314-1996. |
