The synthesis of bis-hydrogenated rosin diglycidyl succinate

Bis-hydrogenated rosin diglycidyl succinate was synthesized by the reaction of succinie acid and hydrogenated rosin shrinked glyeeride, which was prepared with hydrogenated rosin and epichlorohydrin as raw material. The product was confirmed by IR analysis and the data of hydroxyl value. The reaction conditions were studied with single factor experiment and response surface methodology. A reaction model and the optimum conditions were got as the results. The optimum synthesis conditions were as follows： reaction time 2.0 h, reaction temperature 150℃, dimethylbenzene amount 10 ml, and molar ratio 2.5 ： 1 （hydro- genated rosin shrinked glyceride ： succinic acid）. Under optimal conditions, the yield of target product was 75%. The kinetic experimental data correlate with the pseudo-first-order kinetic model. Furthermore, the apparent activation energy and the pre-exponential factor of the reaction were 85.76kJ·mol^-1 and 3.83×10^11h^-1, respectively.
