MTsPc催化H2S还原硝基苯反应性能的研究

就工业气休中有害物质Ｈ２Ｓ的综合利用开发进行了有益的探索，采用ＭＴｓＰｃ（Ｍ＝Ｆｅ，Ｃｏ，Ｎｉ，Ｃｕ）做催化剂，水做溶剂，研究了催化剂物种及浓度、碱浓度反应温度对Ｈ２Ｓ还原硝基苯制备苯胺反应性能的影响。结果表明，在诸多催化剂中双核磺化酞菁钴（ＣｏＰｃ－ＰｃＣｏ）催化活性最高，且得到最佳反应条件为：氨水浓度０．６ｍｏｌ／Ｌ，反应温度４０℃，催化剂质量浓度１ｇ／Ｌ，在此条件下苯胺的产率达３５．９％，表明在传统的脱硫工艺上加以技术改造不仅是可行的，而且是有效的。

Study on the reactin of H2S readucing nitrobenzene catalized by MTsPc

This paper had investigated the developping and use of H2S, the toxin in industralgas. For the reduction of nitrobenzene with H2S catalized by MTsPc(M = Fe, Co, Ni, Cu),They had investigated the influence factor such as kind of catalyst, concentration of catalystand amino, and reaction temperature. For the catalized activity, the best was the binuclearcobalt phthalocyanine CoPc－PcCo, the best condition for such a reduction was as following;amino concentration was 0.6 mol/L, reaction temperature was 40 ℃, and catalyst concentration was 1 g/L. The ratio of aniline was 35.9 % under such a reaction condition. Itshowed an effective path for the improving of the old desulfurizing technology.
