Abstract

An object is to provide a hydrofluoroolefin-based or hydrochlorofluoroolefin-based azeotropic or azeotropic-like composition. The azeotropic or azeotropic-like composition contains trans-1-chloro-3,3,3-trifluoropropene and 1-chloro-1,3,3,3-tetrafluoropropene. In the azeotropic or azeotropic-like composition, 1-chloro-1,3,3,3-tetrafluoropropene exists in an effective amount to form an azeotropic or azeotropic-like mixture with trans-1-chloro-3,3,3-trifluoropropene.

First claim

What is claimed is:

1. A composition consisting of trans-1-chloro-3,3,3-trifluoropropene and 1-chloro-1,3,3,3-tetrafluoropropene,
wherein 1-chloro-1,3,3,3-tetrafluoropropene exists in an effective amount to form an azeotropic mixture or an azeotropic-like mixture with trans-1-chloro-3,3,3-trifluoropropene.

2. The composition according to claim 1 ,
wherein 1-chloro-1,3,3,3-tetrafluoropropene is cis-1-chloro-1,3,3,3-tetrafluoropropene, trans-1-chloro-1,3,3,3-tetrafluoropropene, or a mixture thereof.

3. The composition according to claim 1 , consisting of 90.0000 mol % or more and 99.9999 mol % or less of trans-1-chloro-3,3,3-trifluoropropene and 0.0001 mol % or more and 10.0000 mol % or less of cis-1-chloro-1,3,3,3-tetrafluoropropene with respect to a total amount of trans-1-chloro-3,3,3-trifluoropropene and cis-1-chloro-1,3,3,3-tetrafluoropropene.

4. The composition according to claim 1 , consisting of 80.0000 mol % or more and 99.9998 mol % or less of trans-1-chloro-3,3,3-trifluoropropene, 0.0001 mol % or more and 10.0000 mol % or less of cis-1-chloro-1,3,3,3-tetrafluoropropene, and 0.0001 mol % or more and 10.0000 mol % or less of trans-1-chloro-1,3,3,3-tetrafluoropropene with respect to a total amount of trans-1-chloro-3,3,3-trifluoropropene, cis-1-chloro-1,3,3,3-tetrafluoropropene, and trans-1-chloro-1,3,3,3-tetrafluoropropene.

5. An aerosol composition containing the composition according to claim 1 .

6. A cleaning agent containing the composition according to claim 1 .

7. A solvent containing the composition according to claim 1 .

8. A silicone solvent containing the composition according to claim 1 .

9. A foaming agent containing the composition according to claim 1 .

10. A heat-transfer medium containing the composition according to claim 1 .

11. A heat-transfer device containing the heat-transfer medium according to claim 10 .

12. A refrigeration cycle system, a high-temperature heat pump cycle system, or an organic Rankine cycle system including the heat-transfer device according to claim 11 .

13. A heat-transfer method utilizing the refrigeration cycle system or the high-temperature heat pump cycle system according to claim 12 , the heat-transfer method comprising:
performing heat-exchange on a heat-transfer medium containing a composition consisting of trans-1-chloro-3,3,3-trifluoropropene and 1-chloro-1,3,3,3-tetrafluoropropene, wherein 1-chloro-1,3,3,3-tetrafluoropropene exists in an effective amount to form an azeotropic mixture or an azeotropic-like mixture with trans-1-chloro-3,3,3-trifluoropropene with a first fluid to vaporize the heat-transfer medium;
compressing the vaporized heat-transfer medium to form a superheated steam of the heat-transfer medium;
performing heat-exchange on the superheated steam of the heat-transfer medium with a second fluid to liquefy the heat-transfer medium; and
expanding the liquefied heat-transfer medium.

14. An extinguishing agent containing the composition according to claim 1 .

15. A fumigant containing the composition according to claim 1 .

16. A method for converting thermal energy to mechanical or electrical energy utilizing the organic Rankine cycle system according to claim 12 , the method comprising:
performing heat-exchange on a heat-transfer medium containing a composition consisting of trans-1-chloro-3,3,3-trifluoropropene and 1-chloro-1,3,3,3-tetrafluoropropene, wherein 1-chloro-1,3,3,3-tetrafluoropropene exists in an effective amount to form an azeotropic mixture or an azeotropic-like mixture with trans-1-chloro-3,3,3-trifluoropropene with a fluid to vaporize the heat-transfer medium;
extracting the vaporized heat-transfer medium;
expanding the extracted heat-transfer medium to convert thermal energy of the heat-transfer medium to mechanical or electrical energy; and
condensing the converted heat-transfer medium to form a liquefied converted heat-transfer medium.
