羧酸/烯烃酯化合成羧酸酯工艺及催化剂研究进展

Developm enton Esterification Technology by Carboxylic Acid w ith Olefin to Prepare Alkyl Carboxylate and Advance in Catalyst Research

从工艺及催化剂的开发两个方面介绍了由羧酸与烯烃酯化合成羧酸酯工艺的研究进展。所涉及的催化剂包括矿物酸及磺酸、金属硫酸盐、粘土矿物、氧化物、沸石分子筛、杂多化合物及离子交换树脂。离子交换树脂对于乙酸／丙烯和乙酸／１丁烯的酯化反应具有良好的催化活性及稳定性，杂多化合物则是目前最好的乙酸／乙烯酯化反应的催化剂。

The advance in esterification by carboxylic acid w ith olefins to prepare alkylcarboxylate,including esterification technology and the catalysts research is intro duced. The catalystsinclude m ineralacid orsulphuric acid ,m etalsulphate,clay,ox ide,zeolite,heteropoly com pound,ion exchanged resin. Am ong the researched cata lysts,resin has higher activity and better stability for esterification by acetic acidw ith propylene and esterification by acetic acid w ith 1 butene;the heteropoly com pound is considered as the best catalyst for esterification by acetic acid w ith ethy lene by far.
