摘要
介绍了苯胺生产中硝基苯液相催化加氢制苯胺工艺,着重介绍了液相加氢催化剂体系中的镍系催化剂和贵金属催化剂的研究进展。液相催化加氢多采用贵金属催化剂和高活性、制备工艺复杂的催化剂,生产成本较高,开发价廉、高效并能满足绿色化工要求的新型催化剂是今后工作的重点。
Latest researches in catalysts for preparation of aniline by liquid phase catalytic hydrogenation of nitrobenzene were reviewed, including those ICI, MTC and Du Pont. More detailed description was given on nickel and noble metal catalysts. Currently employed catalysts for the liquid-phase hydrogenation are mostly highly-active noble catalysts with complicated preparation process and higher cost. Development of low-cost, high-efficiency catalysts, which meet the requirement of green chemistry, will be the trends in this aspect.
