Abstract

The present disclosure relates to compositions comprising Z-1,1,1,4,4,4-hexafluoro-2-butene and additional compounds that may be useful as refrigerants, heat transfer compositions, aerosol propellants, foaming agents, blowing agents, solvents, cleaning agents, carrier fluids, displacement drying agents, buffing abrasion agents, polymerization media, expansion agents for polyolefins and polyurethane, gaseous dielectrics, power cycle working fluids, extinguishing agents, and fire suppression agents in liquid or vapor form.

First claim

What is claimed is:

1. A composition comprising Z-HFO-1336mzz and at least one additional compound selected from the group consisting of HCFO-1334 and HCFO-1333, wherein HCFO-1334 is E-HFO-1334mzz, Z-HFO-1334mzz, or combinations thereof; HCFO-1333 is E-HFO-1333mzz, Z-HFO-1333mzz, or combinations thereof, and wherein the composition contains less than about 1 weight percent of said at least one additional compound, based on the total weight of the composition.

2. The composition of claim 1 further comprising at least one tracer compound selected from the group consisting of HFC-356, HCFC-123, HCFC-133a, HFC-143a, HCFO-1122, HCFO-1122a, CFO-1316, HCFO-1335, HFO-1345, and HCFO-1326.

3. The composition of claim 1 comprising
Z-HFO-1336mzz, HCFO-1335, and HCFO-1334.

4. The composition of claim 2 wherein the composition comprises from about 1 ppm to about 1000 ppm of the at least one tracer compound.

5. The composition of claim 2 wherein CFO-1316 is E-HFO-1316mxx, Z-HFO-1316mxx, or combinations thereof.

6. The composition of claim 2 wherein HCFO-1335 is E-HCFO-1335mzz, Z-HFO-1335mzz, E-HCFO-1335mzx, Z-HFO-1335mzx, or combinations thereof.

7. The composition of claim 2 wherein HFO-1345 is E-HFO-1345mzz, Z-HFO-1345mzz, HFO-1345 cm, or combinations thereof.

8. The composition of claim 2 wherein HCFO-1326 is E-HFO-1326mxz, Z-HFO-1326mxz, or combinations thereof.

9. The composition of claim 1 wherein the at least one additional compound is HCFO-1334.

10. The composition of claim 1 wherein the at least one additional compound is HCFO-1333.

11. A method for producing cooling comprising evaporating the composition of claim 1 in the vicinity of a body to be cooled, and thereafter condensing said composition.

12. A method for producing heat comprising condensing the composition of claim 1 in the vicinity of a body to be heated, and thereafter evaporating said composition.

13. A method of forming a foam comprising: (a) adding to a foamable composition the composition of claim 1 ; and (b) processing the composition produced in step (a) under conditions effective to form a foam.

14. A process for producing aerosol products comprising the step of adding the composition of claim 1 to a formulation, including active ingredients in an aerosol container, wherein said composition functions as a propellant.

15. A process for converting heat to mechanical energy comprising heating a working fluid comprising the composition of claim 1 and thereafter expanding the heated working fluid.
