Abstract：The 1,4-butanediol diacrylate was synthesized and its reaction kinetic model was studied using 1,4-butanediol and acrylic acid catalyzed by solid superacid SO42-/TiO2-SnO2. The effects of the concentration of acrylic acid, 1,4-butanediol and water on the initial reaction rate have also been investigated. Based on Elay-Rideal mechanism, the kinetic model for the solid super acid catalyst synthesis process has been established and proved to be validated though the experiments and mathematical methods. The results showed excellent accuracy of the experimental verification model. The relative errors between the values predicted by the model and those from the actual experiment was less than 5% which provided good predication for optimization of the synthesis process of 1,4-butanediol diacrylate.
