摘要:

用固体酸代替硫酸作为酯化反应的催化剂制备酯基碳数为１２～１６的丙烯酸酯类单体，固体酸用量为０．２％，酯产率高达９５．１％，产物不必进行碱洗、水洗等工序，后处理简单、环境污染小，对设备腐蚀小。并考察其聚合物对柴油的降凝作用。

Abstract:

Under the catalytic action of solid acid instead of sulphuric acid,the n-alkylacrylate with the carbon numbers of the alkyl side chain C 12 -C 16 were synthesized with yields of 95.1%,and the product needn't wash with alkali and water.In addintio
