大孔磺酸-Lewis酸复合树脂催化酯化反应的研究

Studies on Performance of Catalytic Esterification of Great Hole Sulfonic Acid-Lewis Acid Complex Resin

研究了 2 0℃时 ,醋酸酐与九种酚在复合树脂催化剂下的催化酯化反应 ,并探索了其反应的机理 .结果表明 ,复合树脂催化剂对反应有显著的催化作用 ,苯环上的各基团 。

The catalytic esterification of acetic anhydride and nine phenols were investigated in the presence of complex resin catalyst at 20 ℃,and its mechanismes were discussed. The results indicate that esterification had been outstanding progress under the catalyst of complex resin. The groups of benzene have some influence upon esterification of phenol.
