The transesterification reaction prepared SIPE was conducted with SIPM and EG. The conversion rate was determined by HPLC. The influence of the synthetic technology on the transesterification rate of SIPE,such as temperature,time,catalyzer type and addition,molar ratio of EG/ SIPM were studied by HPLC. The result revealed the optimum technology is as following : EG/SIPM molar ratio 10.6, catalyzer0.4% Zn (Ac) 2,175 ℃ ,2h.
