摘要
在自己合成的沸石催化剂上加以助催化剂,进行甲苯氯化反应,得到了一氯甲苯产物中～90％的对氯甲苯.在40ml甲苯规模上,考查了一些因素的变化对于混一氯甲苯中对位选择性的影响.反应产物经简单分离后,得到了纯度>98%的对氯甲苯.
chlorination of toluene with zeolite catalyst which is synthesised by ourself and cocatalyst has been studied . The selectivity of p—chloro—toluene based on chloro—toluene products is about 90% . On a 40ml toluene scale, the effects of some changing factors on selectivity has been inves tigated. The products being separated simply , p—chloro—toluene of more than 98% purith is obtained.
