| 摘 要： | 羰基硫(COS)和CO2有非常相似的结构,遵循同样的反应机理,然而在醇胺溶液中COS的反应速率要低得多,COS和伯胺、仲胺的反应通过两性离子和三分子反应机理来描述,和叔胺的反应通过碱催化水解机理来描述。另外还综述了大量关于COS和醇胺溶液反应的动力学研究结果,结合相关研究指出混合醇胺溶液的研究将是未来的发展方向。

| Abstract: | Carbonyl sulfide （COS） and carbon dioxide （CO2） have the same reaction mechanism because of their similar molecular structures, however the reaction rate of carbonyl sulfide is extremely low. Research on the reaction of COS and primary and secondary amine usually is based on the zwitterions reaction mechanism and three molecular reaction mechanism, while research on the reaction of COS and tertiary amine is based on the alkali catalytic hydrolysis mechanism. The development direction is research of the hydramine solutions which are composed with other ingredients by research on the kinetics of COS and hydramine solutions. |
