Abstract

This invention relates to azeotrope-like compositions, methods and systems having utility in numerous applications, and in particular, uses for azeotrope-like compositions comprising effective amounts of the compound cis-1,1,1,4,4,4-hexafluoro-2-butene (Z-HF0-1336mzzm), which has the following structure:

and another material selected from the group consisting of water, fluoroketones, alcohols, hydrochlorofluoroolefins, and combinations of two or more thereof. These compositions may be used in a wide variety of applications such as, blowing agents, refrigerants, heating agents, power cycle agents, cleaning agents, aerosol propellants, sterilization agents, lubricants, flavor and fragrance extractants, flammability reducing agents, and flame suppression agents.

First claim

What is claimed is:

1. An azeotrope-like composition comprising from greater than 59.4 wt % to 97.1 wt % of the compound cis-1,1,1,4,4,4-hexafluoro-2-butene (Z-HFO-1336mzzm) and from 2.9 wt % to less than 40.6 wt % of water.

2. The azeotrope-like composition of claim 1 comprising from about 62.9 wt % to 97.1 wt % of Z-HFO-1336mzzm and from 2.9% to about 37.1 wt % of water.

3. The azeotrope-like composition of claim 1 comprising from 2.9 wt % to about 28.5 wt % of water and from about 71.5wt % to about 97.1 wt % of Z-HFO-1336mzzm.

4. The azeotrope-like composition of claim 3 comprising from 2.9 wt % to about 17.2wt % of water.

5. The azeotrope-like composition of claim 1 comprising from 2.9 wt % to about 10.2wt % of water.

6. A blowing agent comprising an azeotrope-like composition of claim 1 .

7. A method of forming a foam comprising adding to a foamable composition a blowing agent comprising an azeotrope-like composition of claim 1 .

8. A premix of a polyol and a blowing agent wherein the blowing agent comprises an azeotrope-like composition of claim 1 .

9. A closed cell foam prepared by foaming a foamable composition in the presence of a blowing agent comprising the azeotrope-like composition of claim 1 .

10. A refrigerant composition comprising an azeotrope-like composition of claim 1 .

11. A refrigeration system comprising a refrigerant composition of claim 10 .

12. A sprayable composition comprising a material to be sprayed and a propellant comprising an azeotrope-like composition of claim 1 .

13. A method of suppressing a flame comprising contacting said flame with a fluid comprising an azeotrope-like composition of claim 1 .

14. A centrifugal chiller working fluid comprising an azeotrope-like composition of claim 1 .

15. A power cycle working fluid comprising an azeotrope-like composition of claim 1 .

16. The azeotrope-like composition of claim 1 wherein the boiling point of the composition is less than the boiling point of Z-HFO-1336mzzm.

17. The azeotrope-like composition of claim 1 wherein the boiling point of the composition is from 31.4° C. to about 32° C. at a pressure of 14.5 psia.

18. The azeotrope-like composition of claim 1 wherein the boiling point of the composition is less than the boiling point of said Z-HFO-1336mzzm and less than the boiling point of said water.

19. The azeotrope-like composition of claim 18 consisting essentially of said Z-HFO-1336mzzm and said water.

20. The azeotrope-like composition of claim 19 wherein the boiling point of the composition is from 31.4° C. to about 32° C. at a pressure of 14.5 psia.
