摘　　要：研究了把稀土硫酸盐分别固载于人造沸石、活性炭和强酸型阳离子树脂作为酯化催化剂 ,从中选出了比较好的酯化催化剂——强酸型阳离子树脂固载稀土催化剂 ,使合成乙酸正丁酯的产率达到 97.2 % ,并对该催化剂的催化性能进行了较详细的研究。The man made zeolite,active carbon and cation exchange resin carried rare earth sulfate were used as catalysts for the synthesis of butyl acetate.Among these catalysts cation exchange carried catalyst(Ⅲ) showed the highest catalytic activity,with which a reaction yield of 97% was obtained.The catalytic property of catalyst(Ⅲ)was studied in detail.
