AZEOTROPE COMPOSITIONS COMPRISING E-1,3,3,3-TETRAFLUOROPROPENE AND HYDROGEN FLUORIDE AND USES THEREOF.

摘要

Disclosed herein are azeotrope and near-azeotrope compositions comprising iE/i-1,3,3,3-tetrafluoropropene and hydrogen fluoride. These azeotrope and near-azeotrope compositions are useful in processes to produce iE/i-1,3,3,3-tetrafluoropropene and in processes to purify iE/i-1,3,3,3-tetrafluoropropene from mixtures of iE/i-1,3,3,3-tetrafluoropropene with 1,1,1,3,3-pentafluoropropane and/or with hydrogen fluoride.
