就工业气体中有害物质H2 S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、碱浓度和反应温度对H2 S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 4 0℃ ,催化剂质量浓度 1 g/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
This paper explored the comprehensive utilization of H2S, an industrial gas, by using MTsPc (M = Fe, Co, Ni, Cu) as catalyst and water as solvent, and studied the species and concentration of catalyst, the concentration of alkali and the reaction temperature On H2S reduction of nitrobenzene to prepare aniline.The results showed that the catalytic activity of binuclear sulfonated cobalt phthalocyanine (CoPc-PcCo) was the highest and the optimal reaction conditions were as follows: ammonia concentration of 0 6mol / L , The reaction temperature is 40 ℃ and the catalyst concentration is 1 g / L. The yield of aniline in this condition is 35 9%, which shows that it is not only feasible but also effective to reform the traditional desulfurization process
