Abstract
Official abstract text for this publication.
An azeotropic-like composition containing 2-chloro-1,3,3,3-tetrafluoropropene and 1-chloro-3,3,3-trifluoropropene is provided. The azeotropic-like composition according to the present invention is non-flammable, has little influence on the environment, and has substantially the same composition ratio in the liquid phase and the gas phase. By use of an azeotropic-like composition according to the present invention, a washing detergent, a solvent, a silicone solvent, a foaming agent, a coolant, a heating medium for a heat pump, and a high temperature working fluid that are non-flammable, have little influence on the environment, and have substantially the same composition ratio in a liquid phase and a gas phase thereof may be provided.
First claim
Opening claim text (preview).
What is claimed is: 1. An azeotropic-like composition consisting essentially of 2 chloro-1,3,3,3-tetrafluoropropene and 1-chloro-3,3,3-trifluoropropene. 2. The azeotropic-like composition according to claim 1 , wherein the azeotropic-like composition has trans-2-chloro-1,3,3,3-tetrafluoropropene and trans-1-chloro-3,3,3-trifluoropropene. 3. The azeotropic-like composition according to claim 2 , wherein the trans-1-chloro-3,3,3-trifluoropropene is contained at a content of 1 mol % or greater and 99.999 mol % or less, and the trans-2-chloro-1,3,3,3-tetrafluoropropene is contained at a content of 0.001 mol % or greater and 99 mol % or less. 4. The azeotropic-like composition according to claim 1 , wherein the azeotropic-like composition has cis-2-chloro-1,3,3,3-tetrafluoropropene and trans-1-chloro-3,3,3-trifluoropropene. 5. The azeotropic-like composition according to claim 4 , wherein the cis-2-chloro-1,3,3,3-tetrafluoropropene is contained at a content of 0.001 mol % or greater and 99.999 mol % or less, and the trans-1-chloro-3,3,3-trifluoropropene is contained at a content of 0.001 mol % or greater and 99.999 mol % or less. 6. The azeotropic-like composition according to claim 1 , wherein the azeotropic-like composition has trans-2-chloro-1,3,3,3-tetrafluoropropene and cis-1-chloro-3,3,3-trifluoropropene. 7. The azeotropic-like composition according to claim 6 , wherein the trans-2-chloro-1,3,3,3-tetrafluoropropene is contained at a content of 90 mol % or greater and 99.9 mol % or less, and the cis-1-chloro-3,3,3-trifluoropropene is contained at a content of 0.1 mol % or greater and 10 mol % or less. 8. The azeotropic-like composition according to claim 1 , wherein the azeotropic-like composition has trans-2-chloro-1,3,3,3-tetrafluoropropene, cis-2-chloro-1,3,3,3-tetrafluoropropene and trans-1-chloro-3,3,3-trifluoropropene. 9. The azeotropic-like composition according to claim 1 , wherein the azeotropic-like composition has trans-2-chloro-1,3,3,3-tetrafluoropropene, cis-2-chloro-1,3,3,3-tetrafluoropropene, trans-1-chloro-3,3,3-trifluoropropene, and cis-1-chloro-3,3,3-trifluoropropene. 10. A washing detergent comprising the azeotropic-like composition according to claim 1 . 11. A solvent comprising the azeotropic-like composition according to claim 1 . 12. A silicone solvent comprising the azeotropic-like composition according to claim 1 . 13. A foaming agent comprising the azeotropic-like composition according to claim 1 . 14. A heat transfer medium comprising the azeotropic-like composition according to claim 1 . 15. A heat transfer device using the heat transfer medium according to claim 14 . 16. An organic rankine cycle system using the heat transfer medium according to claim 14 . 17. A high temperature heat pump cycle system using the heat transfer medium according to claim 14 . 18. A refrigeration cycle system using the heat transfer medium according to claim 14 . 19. The azeotropic-like composition according to claim 1 , wherein the azeotropic-like composition consists of 2-chloro-1,3,3,3-tetrafluoropropene and 1-chloro-3,3,3-trifluoropropene. 20. The washing detergent according to claim 10 further comprising a surfactant. 21. The heat transfer medium according to claim 14 further comprising a lubricant, a stabilizer or a flame retardant. 22. A washing detergent comprising the azeotropic-like composition according to claim 19 . 23. A heat transfer medium comprising the azeotropic-like composition according to claim 19 . 24. The washing detergent according to claim 22 further comprising a surfactant. 25. The heat transfer medium according to claim 23 further comprising a lubricant, a stabilizer or a flame retardant.
