Abstract:
The invention relates to the separation of a mixture comprising 2-chloro-1,1-difluoroethane (R142) and trans-dichloroethylene (TDCE) by extractive distillation and more particularly to a separation process wherein the TDCE is removed selectively by extractive distillation, thus leading to purified 2-chloro-1,1-difluoroethane.
