催化加氢法制备3-氯-2-甲基苯胺
A Study on the Synthesis of 3-Chloro-2-methylaniline by Catalytic Hydrogenation
【摘要】 以2-氯-6-硝基甲苯为原料,经催化加氢还原制备3-氯-2-甲基苯胺。以W4型雷尼镍为催化剂,在助催化剂存在下研究了影响催化加氢反应的主要因素。在优化条件下,得到的产品纯度高于99%,收率高于95%。
【Abstract】 In this paper, 3-chloro-2-methylaniline was synthesized by catalytic hydrogenation from 2-chloro-6-nitrotoluene; On the case of the catalytic and the major factors which influence the reaction were studied. Underoptimum conditions, the purity of the product is above 99%, and the yied is about 95%.
