| Heterogeneous Catalytic Esterification for the Production of Butyl Acrylate by Using Solid Superacid |
| LIU Ping-le etc.（School of Chemical Engineering; Xiangtan University; Hunan Xiangtan; 411105; China） |
| Abstract：Catalytic esterification of acrylic acid and butyl alcohol for the production of butyl acrylate in batch stirred tank by using solid superacid was presented. Some different kinds of solid superacid, the influence of stir speed, the amount of catalyst, and the roasting temperature on esterification reaction was studied. The results show that the TiO 2/SO 2- 4 solid superacid under the reaction condition of 363.15～373.15 K has the best catalytic effect. |
| Key words：solid superacid; catalytic esterification; butyl acrylate |
