N－异丙基邻甲苯胺催化合成──芳胺N－烷基化研究（Ⅱ）

CATALYTIC SYNTHESIS OF N-ISOPROPYL-O-TOLUIDINE──N-AKYLATION OF AROMATIC AMINE SERIES(Ⅱ)

本文研究了以硫酸为主催化剂、镍系过渡金属为助催化剂的中压液相催化法合成Ｎ－异丙基邻甲苯胺．这种共同催化法不仅反应条件温和而且收率达到了７３．７％．比现行工业上采用的硫酸催化法收率提高了１６％．同时对影响反应的助催化剂、反应物的配比等进行了分析与讨论．

In this paper the N-isopropyl-O-toluidine has been synthesized by means of co-catalysis used sulfuric acid as main catalyst and Nickel salt as catalytic promoter. This Co -catalysis is mild in reaction condition, and yield is higher than one of sulfuric acid as only catalyst, reaches 73. 7%.
