摘要
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 。
This paper had investigated the developping and use of H 2S, the toxin in industral gas. For the reduction of nitrobenzene with H 2S catalized by MTsPc(M=Fe,Co,Ni,Cu), They had investigated the influence factor such as kind of catalyst, concentration of catalyst and amino, and reaction temperature. For the catalized activity, the best was the binuclear cobalt 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. It showed an effective path for the improving of the old desulfurizing technology.
