摘　　要：用骨架镍催化加氢制备间-（β-羟乙基砜）苯胺,反应条件温和、催化剂使用成本低,能替代铁粉还原法。本文对催化剂用量和复用进行了试验研究,讨论了浓度、温度、压力等因素对加氢反应的影响。m-(β-Hydroxyethyl sulfonyl)aniline was prepared by Raney nickel catalytic hydrogenation instead of iron reduction. The operation cost of this method was low and reaction conditions were moderate. The life and quantity of the catalyst were studied and factors involving the reactions such as concentration, temperature and pressure discussed.
