| 摘 要： | 1,1,2-三氟三氯乙烷(CFC-113)是亟需淘汰的消耗臭氧层物质(ODS)之一,而其同分异构体1,1,1-三氟三氯乙烷却属于非ODS物质。介绍了以CFC-113为原料转产为CFC-113a的技术进展,并使用了一种新型添加剂和调节剂,使其转化率达到了99.5%以上,极大地提高了产率。并且省去了精馏的过程,节约了成本。

| Abstract: | 1,1,2-trifluoro-trichloroethane (CFC-113) is a much-needed phase-out ozone-depleting substances (ODS), one of its isomers 1,1,1-trifluoro-trichloroethane is non-ODS substances. This paper introduces the technological advances of CFC-113 as the raw material converting to CFC-113a, and the use of a new type of additives and conditioning agents to conversion rate of 99.5%, and greatly improves yield. At the same time,eliminating the need for distillation process, saving costs. |
