Abstract: Liquid 1,1-dichloro-1-fluoroethane containing contaminating unsaturated carbon compounds is treated with chlorine and ultraviolet light to convert the unsaturated contaminants to photochlorination products. The photochlorination products are thereafter separated from 1,1-dichloro-1-fluoroethane, such as by distillation. The process is particularly useful in separating vinylidene chloride from 1,1-dichloro-1-fluoroethane.

Abstract: Process for synthesizing 1,1,1-trifluoroethane (143a) in the gaseous phase by reacting 1,1-defluoro-1-chloroethane in gaseous phase in the presence of a Cr catalyst. The process may be run isothermally or adiabatically, without co-feeding air or other oxygen containing gas, in the presence or absence of a Ni, Co, Zn or Mn cocatalyst for the Cr catalyst. The catalyst may be unsupported or supported with a support preferably selected from activated carbon, alumina and fluorided alumina. The formation of olefin byproduct can be kept to less than 10 ppm in accordance with the process of the invention.
Abstract translation: 通过使1,1-二氟-1-氯乙烷在气相中在Cr催化剂存在下反应合成气相中的1,1,1-三氟乙烷（143a）的方法。 该方法可以在存在或不存在用于Cr催化剂的Ni，Co，Zn或Mn助催化剂的情况下等温或绝热地运行，而无需共同进料空气或其它含氧气体。 所述催化剂可以不被载体或载体优选选自活性炭，氧化铝和氟化氧化铝。 根据本发明的方法，可以将烯烃副产物的形成保持在小于10ppm。
