In this paper, gas phase catalytic hydrogenation technology to the preparation ofm-toluidine from m-nitrotoluene was studied. 本课题以间硝基甲苯为原料,对间硝基甲苯气相加氢制备间甲苯胺工艺进行了研究。
Hydrogenation of m-Nitrotoluene to m-Toluidine over Amorphous Ni-B Alloy Catalyst Ni-B非晶态合金催化加氢制备间甲苯胺
Types and synthesis routes of the derivatives from m-nitrotoluene were introduced, and conversion and application ofm-nitrotoluene were discussed in the paper. 阐述了间硝基甲苯下游产品的种类及开发途径,对间硝基甲苯的转化利用进行了深入的研究。
The reaction occurs under very mild conditions and when the mole ratio of alkaline salt of phenol to nitrotoluene is 4:1, quantitative yield of nitrophenylacetic acid may be obtained. The carboxylation of m-nitrotoluene fails under the same conditions. 反应条件温和。当碱金属酚盐与硝基甲苯的摩尔配比为4:1时,可获得定量收率的硝基苯乙酸,间硝基甲苯在同样的条件下不能进行反应。
The results show that the catalytic activity of C-MWNTs for the electroreduction of m-nitrotoluene is good; 实验结果表明:C-MWNT-PME对间硝基甲苯具有良好的电催化活性;
The stability of the C-MWNT-PME during the process of the electroreduction of m-nitrotoluene was investigated, and the results show that it owns good stability during the process of the electroreduction of m-nitrotoluene in acid solution. 在实验基础上,进一步分析研究了C-MWNT-PME在间硝基甲苯电还原过程中的稳定性,结果表明,酸性溶液中C-MWNT-PME在间硝基甲苯电还原过程中是稳定的。
