Abstract
The invention relates to a separation process whereby 2-chloro-3,3,3-trifluoropropene (1233xf) is separated from a mixture containing other fluorinated organics and high boiling materials such as dimers using azeotropes of HF formed by adding appropriate amounts to the mixture which facilitate separation by, e.g. distillation.
