Disclosed herein is an azeotrope or azeotrope-like composition comprising 3,3,3-trifluoropropene and hydrogen fluoride. Also disclosed herein are processes for separating 3,3,3-trifluoro-propene and hydrogen fluoride by azeotrop-ic distillation both with and without an added entrainer compound. Also disclosed herein are processes for separating 1,1,1, 2-tetrafluoropropane and/or 1,1,1, 3-tetrafluoropropane, and 3,3,3-trifluoropropene from hydrogen fluoride by azeotropic distillation both with and without an added entrainer.
