摘要
介绍了苯胺生产技术现状及产品市场情况,重点总结了硝基苯催化加氢制苯胺工艺的贵金属催化剂、非贵金属催化剂、光催化剂、工艺优化等方面的技术进展。与其他苯胺生产技术相比,硝基苯催化加氢制苯胺仍是最主要的生产工艺。同时对国内外苯胺产品市场情况进行了分析,结果表明:全球苯胺产业仍将呈现正增长,但国内苯胺供大于求,行业洗牌加速,将向大型化、绿色化转型,上下游一体化发展格局凸显。
The current development of aniline production technology and product market situation were reviewed,focusing on summarizing the technological progress of catalytic hydrogenation of nitrobenzene to aniline in terms of noble metal catalyst,non-noble metal catalyst,photocatalyst,process optimization,etc.Comparing with other aniline production technologies,it was pointed out that the catalytic hydrogenation of nitrobenzene to aniline is still the most dominant aniline production process.In addition,the domestic and overseas aniline product market situation was analyzed,and the results showed that the global aniline industry still shows positive growth,but the domestic aniline supply exceeds the demand,leading to acceleration of industry reshuffle,which means that the aniline industry will transform to green and large-scale,and the development pattern of upstream and downstream integration will be prominent.
