Abstract

The invention relates to a composition including 1,1,1,4,4,4-hexafluorobut-2-ene and 3,3,4,4,4-pentafluorobut-1-ene, as well as to use thereof, in particular as a heat transfer fluid.

First claim

The invention claimed is:

1. A composition consisting of:
from 10% to 60% of trans-1,1,1,4,4,4-hexafluorobut-2-ene;
from 40% to 90% of 3,3,4,4,4-pentafluorobut-1-ene; and
optionally one or more additives selected from the group consisting of lubricants, stabilizers, surfactants, tracers, fluorescent agents, odorous agents solubilizing agents, and mixtures thereof, wherein the composition is azeotropic or azeotrope-like.

2. A heat-transfer fluid comprising the composition as claimed in claim 1 .

3. The composition as claimed in claim 1 , the composition including the one or more additives selected from the group consisting of lubricants, stabilizers, surfactants, tracers, fluorescent agents, odorous agents solubilizing agents, and mixtures thereof.

4. Heat-transfer equipment comprising a vapor compression circuit containing a composition as claimed in claim 1 as a heat-transfer fluid.

5. The heat-transfer equipment as claimed in claim 4 , selected from the group consisting of mobile heat-pump heating, stationary heat-pump heating, air conditioning, refrigeration equipment, freezing equipment and Rankine cycles.

6. A blowing agent comprising the composition as claimed in claim 1 and one or more compounds capable of reacting and forming a foam or cellular structure.

7. A propellant comprising the composition as claimed in claim 1 and an aerosol.

8. The composition as claimed in claim 1 , wherein the trans-1,1,1,4,4,4-hexafluorobut-2-ene is from 20% to 60% and the 3,3,4,4,4-pentafluorobut-1-ene is from 40% to 80%.

9. The composition as claimed in claim 1 , wherein the trans-1,1,1,4,4,4-hexafluorobut-2-ene is from 40% to 60% and the 3,3,4,4,4-pentafluorobut-1-ene is from 40% to 60%.

10. The composition as claimed in claim 1 , wherein the trans-1,1,1,4,4,4-hexafluorobut-2-ene is from 45% to 55% and the 3,3,4,4,4-pentafluorobut-1-ene is from 45% to 55%.

11. The composition as claimed in claim 1 , wherein the trans-14,1,4,4,4-hexafluorobut-2-ene is from 15% to 50% and the 3,3,4,4,4-pentafluorobut-1-ene is from 50% to 85%.

12. The composition as claimed in claim 1 , wherein the trans-1,1,1,4,4,4-hexafluorobut-2-ene is from 15% to 30% and the 3,3,4,4,4-pentafluorobut-1-ene is from 70% to 85%.

13. A process for heating or for cooling a fluid or a body by means of a vapor compression circuit containing a heat-transfer fluid, said process successively comprising evaporation of the heat-transfer fluid, compression of the heat-transfer fluid, condensation of the heat-transfer fluid and expansion of the heat-transfer fluid, wherein the heat-transfer fluid is a composition as claimed in claim 1 .

14. The process as claimed in claim 13 , which is a process for cooling a fluid or a body, wherein the temperature of the fluid or of the body cooled is from −15° C. to 15° C.

15. A process for reducing the environmental impact of heat-transfer equipment comprising a vapor compression circuit containing an initial heat-transfer fluid, said process comprising a step of replacing the initial heat-transfer fluid in the vapor compression circuit with a final heat-transfer fluid, the final heat-transfer fluid having a GWP which is lower than the initial heat-transfer fluid, wherein the final heat-transfer fluid is a composition as claimed in claim 1 .

16. The process as claimed in claim 13 , which is a process for heating a fluid or a body, wherein the temperature of the fluid or of the body heated is from 30° C. to 90° C.
