A process for preparation of tripentaerythritol octaacrylate by direct esterification from tripentaerythritol and acrylic acid was studied.The effects of the types and amount of catalysts and inhibitors,amount of solvent,molar ratio of acid to alcohol and reaction time were investigated.The optimum reaction conditions were determined as follows: Solid superacid SA2.0 g,inhibitor YD 0.8 g,toluene 95mL,molar ratio of acid to alcohol 10∶1,reflux 4 h.The ...
