1,1-二氟乙烷生产中氯乙烯脱除技术研究进展

Vinylchloride Removal Progress in the Production of 1,1-Difluoroethane

介绍了以氯乙烯为原料生产1,1-二氟乙烷中,脱除氯乙烯的必要性。在净化、精 馏2个阶段采用不同的方法,可将氯乙烯体积分数降至10×10-6以下。

Necessity of chloroethylene removal of in the production of 1, 1 - difluoroethane from chloroethylene is introduced. On two different stages of purification and rectification different methods are used to reduce volume fraction of chloroethylene to less than 10×10-6.
