the present disclosure provides separation processes that use azeotropic or azeotropic - like compositions of 1 - chloro - 3 , 3 , 3 - trifluoropropene that allow for improved recovery rates of 1 - chloro - 3 , 3 , 3 - trifluoropropene during or after manufacturing processes . such recovery or separation processes can utilize the unique properties of azeotropic or azeotropic - like composition with various combinations of separation techniques that yield highly pure compositions of 1 - chloro - 3 , 3 , 3 - trifluoropropene and simultaneously offer high yields of 1 - chloro - 3 , 3 , 3 - trifluoropropene . such highly pure compositions of 1 - chloro - 3 , 3 , 3 - trifluoropropene may find useful applications in polymer technology as monomers or comonomers .
