Abstract:

A synthesis method of cheap and nontoxic plasticizer was studied.Epoxidized soybean oil methyl esters was prepared by abandoned soybean oil stocks, FT-IR and 1HNMR were employed to characterize the production. The optimum epoxidisation process was optimized by single-factor experiment and orthogonal experiment, m(soybean oil methyl esters):m(formic acid);m(hydrogen peroxide)=1:0.2:0.65,reaction temperature was 35℃,reaction time was 5.5h.The epoxy value of the final product under these conditions was 4.59%,and it was light color and stable quality.This product process provided a new way for using abandoned soybean oil stocks as environmental-friendly plasticizer.
