间苯二胺生产工艺的研究进展

介绍了以间二硝基苯为主要原料生产间苯二胺的3种方法,即化学还原法、催化加氢法和电解还原法。对以贵金属催化剂和非贵金属催化剂通过催化加氢制备间苯二胺的方法作了详细综述,该方法也是间苯二胺的主要生产方法,并对今后的研究方向提出了建议。

Research Progress of m-Phenylenediamine Preparation Techniques

Three techniques for preparing m - phenylenediamine with m - dinitrobenzene as the material, i.e. chemical reduction technique, catalytic hydrogenation technique and electrolytic reduction technique, are introduced, with the emphasis on the introduction of the m- phenylenediamine preparation technique of cata- lytic hydrogenation, the major production technique of m - phenylenediamine, under the action of noble metal catalyst or non - noble metal catalyst, and some suggestions concerning future research of m - phenylenedia- mine preparation technique are presented in this paper.
