FIELD: organic chemistry, chemical technology. SUBSTANCE: separation is carried out on column by extractive distillation in the presence of extract. Top fraction consisting of mainly hydrogen chloride and bottom fraction consisting of tetrafluoroethylene and extract were isolated. Perhalogenated hydrocarbon, in part, perfluorocyclobutane, hexafluoropropylene or 1,1,1-trifluoro-1,2,2-trichloroethane were used as extractants. EFFECT: improved method of separation. 12 cl
