摘要
介绍了国内外硫化氢甲醇法合成甲硫醇工艺发展状况和工业化进程,探讨了工艺反应机理,提出了反应的关键影响因素是降低甲醇上羟基碱性和增强硫化氢亲核性能。文章重点讨论了工艺所用催化剂类型、催化作用机理以及催化剂研究进展,并指出酸碱催化理论在工艺中的重要应用。
The development and industrialization process in methyl mercaptan synthesis with hydrogen sulfide and methanol in domestic and international field were introduced. The reaction mechanism for the process was dis- cussed, and the key points of reaction were to reduce the alkaline of hydroxy on methanol and enhance nucleophilic performance of hydrogen sulfide. The type of catalyst, catalytic mechanism and research progress on catalyst were mainly discussed, and the application of acid and alkali catalytic theory in the progress was emphasized in this paper.
