FIELD: chemistry.
SUBSTANCE: invention relates to triple azeotrope-like composition for obtaining 1-chloro-3,3,3-trifluoropropylene, which contains from approximately 24 to approximately 45 wt % of 1,1,1,3,3-pentafluoropropane, from approximately 42 to 65 wt % of 1-chloro-3,3,3-trifluoropropylene and from 0.5 to approximately 22 wt % of hydrogen fluoride. Invention also relates to method of obtaining 1-chloro-3,3,3-trifluoropropylene.
EFFECT: claimed composition contains flowing galloid-derived media with low potential of ozone depletion and low potential of global warming.
