摘要
针对目前硝基苯、二硝基甲苯催化加氢生产苯胺、甲苯二胺工艺存在的安全隐患和催化剂金属原子利用率低等问题,基于原子尺度金属催化剂和液相有机氢载体构建具有本质安全、环境友好及贵金属减量化等特征的硝基苯、二硝基甲苯催化加氢反应体系。介绍了不锈钢基单原子铂金属催化剂制备方法及在硝基苯加氢反应中的应用,异丙醇为氢源的二硝基甲苯加氢-异丙醇脱氢耦合液相反应催化剂及合成甲苯二胺反应性能,活性金属烧结膜反应器及液相微连续流催化加氢合成苯胺、甲苯二胺反应性能,以及锆基材质上纳米管(坑)阵列铂催化剂制备及合成甲苯二胺反应性能等方面的研究结果;为苯胺、甲苯二胺的绿色安全生产提供了基础。
The current process of catalytic hydrogenation of nitrobenzene and dinitrotoluene to produce aniline and toluene diamine have the drawbacks of safety hazards and low utilization rate of catalyst metal atoms.To deal with these problems,we suggest a reaction system with the intrinsic safety,environmen-tally friendly which reduces the amount of catalytic precious metals based on the atomic-scale features of supported metal catalysts and liquid-organic hydrogen carrier.This paper reports some catalysts and eval-uates the catalytic performance of toluene diamine,such as the preparation method of stainless steel-based single-atom platinum metal catalyst and its application in the hydrogenation of nitrobenzene,a cata-lyst for the coupled liquid phase reaction of dinitrotoluene hydrogenation-isopropanol dehydrogenation with isopropanol as the hydrogen source to synthesize toluene diamine,active metal sintered membrane reactor and liquid-phase micro-continuous flow catalytic hydrogenation synthesis of aniline and toluene diamine,and preparation of nanotube(pit)array platinum catalyst on zirconium-based materials and synthesis of toluenediamine.It provides the basis for green and safe production of aniline and toluenediamine.
