Abstract: Stearone glycol fumaric acid (SGF) was synthesized with maleic anhydride, cinnamyl alcohol and ethylene glycol.There existed a significantly synergic catalysis between BF3 and HCl.During the process of esterification,dripping H2SO4 could increase the yield of SGF.SGF could significantly inhibit the growth of microbe by prolonging the adaptable phase,shortening the logarithmic and stable growth phase,and inducing the autolysis of microorganisms.
