摘　　要：3-(β-羟乙基砜基)苯胺是一种重要的染料中间体。它可以由3-(β-羟乙基砜基)硝基苯还原制得。在高压反应釜中加入Raney-Ni催化剂,在温度90℃、3MPa的氢气压力下,反应4～5小时,制备3-(β-羟乙基砜基)苯胺。该种合成方法工艺简单,质量好,并且不造成环境污染。3-Hydroxyethylsulfonyl-aniline was an important dye intermediate.It could be prepared by reduction reaction of 3-hydroxyethylsulfonyl-nitrobenzene.In the presense of Raney-Ni catalyst,3-hydroxyethylsulfonyl-aniline was prepared in autoclave under the conditions of temperature 90℃, hydrogen pressure 3.0 MPa and reaction time 4-5 hours. This Synthesis method was simple and environally friendly. At the same time, the quality of the product was better.
