摘　　要：Ｌｎ_２Ｏ_３／Ａｌ_２Ｏ_３催化酯化合成邻苯二甲酸二辛酯陈其瑞，张凤美，罗明润，焦肇林（安徽师范大学化学系，芜湖２４１０００）关键词稀土氧化物，担载催化剂，催化酯化，邻苯二甲酸二辛酯邻苯二甲酸二（２－乙基己醇用酯（Ｄｉｏｃｔｙｌｐｈｔｈａｌａｔｅ）是一...he catalytic esterification by rare earth oxides to synthesize dioctyl phthalate was further improved by using the supported catalyst Ln2()3/Al2()3 (Ln=Gd, Ho, Tin and Lu). The catalyst was prepared by coprecipitation-calcination method, the increased catalytic activity was due to the high dispersion of rare earth ions on the surface of Al2()3. On the other hand, the amount of rare earth oxide used in this method was reduced by about90%,so the total production cost was much lowered.
