摘　　要：咪唑类化合物作为一种重要的有机化学原料,在药物合成、功能离子液体、农业、缓蚀剂等领域的应用越来越广泛,近几年国内对其需求量不断增加,但是传统的咪唑工业合成工艺对环境污染较大,现环保政策的推行导致成本过高,企业面临着很大的生产压力。将咪唑啉类化合物催化氧化合成咪唑类化合物不需要高污染的原料,反应过程简单环保,有望改变这一现状,寻求催化性能良好、绿色、经济的催化剂是其中重点。主要从贵金属和非贵金属催化剂两大类介绍总结了现有的国内外咪唑类化合物氧化脱氢催化剂,综合其反应时间、温度、用量等因素做出评价,并对催化剂的未来发展和改进做出了展望。As an important organic chemical raw material,imidazole compounds are more and more widely used in drug synthesis,functional ionic liquids,agriculture,corrosion inhibitors and other fields,and the demand for them has been in⁃creasing in recent years.However,the traditional imidazole industrial synthesis process is polluting to the environment,and the implementation of environmental protection policies has led to high costs,so enterprises are facing great production pressure.The catalytic oxidation of imidazolines to the synthesis of imidazoles does not require highly polluting raw materi⁃als,and the reaction process is simple and environmentally friendly,which is expected to change this situation.Seeking catalysts with good catalytic performance,environmental protection and economy is one of the key points.In this paper,the existing domestic and foreign imidazole oxidative dehydrogenation catalysts are summarized from the two categories of pre⁃cious metal and non-precious metal catalysts,and their reaction time,temperature,dosage and other factors are evalu⁃ated,and the future development and improvement of the catalysts are prospected.
