摘要
通过乙苯的乙酰化反应、还原反应、脱水反应可以制备对乙基苯乙烯 ,其中乙酰化反应是重要步骤。在本工作中 ,采用气相色谱对乙酰化反应过程跟踪测试 ,研究反应条件对收率和选择性的影响 ,优化反应条件。同时 ,以红外光谱。
p -ethyl-styrene was synthesised from ethylbenzene by several steps of Friedel-Crafts acylation,reduction and dehydration.Among which acylation is the more important.The reaction process of acylation was monitored by Gas-chromatography.The effects of solvents,reactants ratio and temperature on the yield and selectivity were determined.Optimization of parameters was got out.The products were identified by methods of IR and 1HNMR.
