摘要
邻氯苯胺是一类重要的精细化工中间体,随着国内外聚氨酯工业的发展,对邻氯苯胺的需求呈现快速上升的趋势,对其研究的方法也逐渐改进。本文就近年来邻氯硝基苯制备邻氯苯胺合成用的催化剂和加氢脱氯副反应的抑制进行了综述。
o-chloroaniline is one kind of important fine chemical intermediates,along with the development of polyurethane industry at home and abroad,the demand of o-chloroaniline presents rapidly rising trend,its research methods also improve gradually.This article summarized the catalysts used in the preparation of o-chloroaniline with o-chloronitrobenzene,and the suppression of hydrodechlorination side reaction.
