摘要
用微波辐射技术以乙酸和正丁醇为原料,强酸性苯乙烯系阳离子交换树脂为催化剂的酯化反应,探索合适的反应条件.实验中,分别从催化剂的用量、微波输出功率、微波辐射时间、投料比四个因素进行实验条件的探索,得出最佳的微波合成条件为:催化剂用量2.0g,酸醇物质的量的比为:1.0∶2.0,微波功率为595W,微波辐射时间为30min,产率84.1%.
The synthesis of butyl acetate is studied under microwave irradiation.Resin is used as catalyst.The yield of butyl acetate could be up to 84.1% under following conditions:1.0:2.0 (mol/mol)of alcohol to acid,2.0 g catalyst and 595 W microwave power which lasts for 30 min.Under the most suitable conditions,butyl acetate is synthesized rapidly by microwave irradiation under normal pressure.
