Catalytic Synthesis of Trimethylolpropane Triacrylate by p-Toluenesulphonic Acid Supported on Activited Carbon

The supported P-Toluenesulphonic acid Catalyst(P-TsOH/C)was prepared with high catalytic activity.It was used as catalyst for esterification of Trimethylolpropane with Acrylic acid.The effection of the ratio of Trimethylolpropane with Acrylic acid,esterificationand the amount of catalyst was discussed and the optimum condition was selected.The conversion of Acrylic Acid was over 95.2%,and the purity of product was over 98%;the catalyst could be used for many times without distinct loss in activity.
