摘　　要：以 D72和 D6 1大孔磺酸型树脂及无水 Al Cl3 为原料 ,采用液固法进行络和反应制备了固体超强酸催化剂。对多种影响因素进行了考查 ,并进行了酯化应用研究。在液 -固络合法中 ,使用了甲醇、乙醇作为溶剂 ,采用乙醇作为溶剂更为适宜。在反应温度 78℃和干燥时间 30 h、反应时间 6 h的条件下 ,该催化剂铝含量可达 2 .78% (质量分数 )。催化酯化结果表明该催化剂对部分羧酸酯化反应具有较好催化作用。Using D72 and D61 macroporous resin and aluminium trichloride,macroporous sulfoacid ion exchange resin aluminium trichloride super acid were prepared by liquid solid solvent method.The effects of various factors were determined and the esterification applications were studied. Adopting liquid solid method,methanol and alcohol were acted as solvent,but alcohol was better.Under the condition of reaction temperature 78℃,dryness time 30h,reaction time 6h,the catalyst containing Al 2.78% was obtained. The results of catalytsis shown that the catalyst has higher catalytic esterification to some carboxylic acid esterification.
