摘要:
A process for separating cis-1,1,1,4,4,4-hexafluoro-2-butene from a first mixture comprising cis-1,1,1,4,4,4-hexafluoro-2-butene and at least one chlorofluoroolefin is disclosed. The process involves the steps of contacting the mixture with at least one extractive agent, to form another mixture, distilling the mixture; and recovering cis-1,1,1,4,4,4-hexafluoro-2-butene substantially free of chlorofluoroolefin.

Disclosed herein are processes for separation of 2,3,3,3-tetrafluoropropene and hydrogen fluoride using azeotropic distillation. Additionally, disclosed are processes for separating mixtures of 2,3,3,3-tetrafluoropropene, hydrogen fluoride and 1,1,1,2,3-pentafluoropropane (HFC-245eb) and/or 1,1,1,2,2-pentafluoropropane (HFC-245cb) by azeotropic distillation.
摘要:
Disclosed is process for the recovery of HFC-43-10mee from a mixture comprising hydrogen fluoride and HFC-43-10mee, comprising feeding the composition comprising hydrogen fluoride and HFC-43-10mee to a distillation column, subjecting said mixture to a distillation step from which is formed a column distillate composition comprising an azeotrope or azeotrope-like composition of hydrogen fluoride and HFC-43-10mee, and a column-bottoms composition comprising HFC-43-10mee, condensing said column distillate composition to form two liquid phases, being i) an HFC-43-10mee-rich phase and ii) an HF-rich phase; and separating said two liquid phases.
摘要:
Disclosed is a process for separating fluoroolefin from a composition comprising HF and fluoroolefin, said process comprising extracting said composition with an extractant. Also disclosed is a composition comprising HF, at least one fluoroolefin, and at least one extractant.
