Abstract

The present disclosure relates to compositions comprising 2,3,3,3-tetrafluoropropene that may be useful as 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, extinguishing agents, and fire suppression agents in liquid or gaseous form. Additionally, the present disclosure relates to compositions comprising 1,1,2,3-tetrachloropropene, 2-chloro-3,3,3-trifluoropropene, or 2-chloro-1,1,1,2-tetrafluoropropane, which may be useful in processes to produce 2,3,3,3-tetrafluoropropene.

First claim

What is claimed is:

1. A composition comprising HCO-1230xa and at least one additional compound selected from the group consisting of propylene, HCO-1260zf, HCC-260da, HCC-260db, HCO-1250xf, HCC-250aa, and HCC-240aa.

2. The composition of claim 1 comprising HCC-240aa.

3. The composition of claim 2 further comprising at least one compound selected from the group consisting of HCC-250aa and HCC-260da.

4. The composition of any one of claims 1 through 3 further comprising HF.

5. The composition of any one of claims 1 through 3 that are acid free.

6. A method for producing cooling comprising evaporating a composition of any of claims 1 through 3 in the vicinity of a body to be cooled, and thereafter condensing said composition.

7. A method for producing heat comprising condensing a composition of any of claims 1 through 3 in the vicinity of a body to be heated, and thereafter evaporating said compositions.

8. A method of forming a foam comprising: (a) adding to a foamable composition a composition of any of claims 1 through 3 ; and (b) processing the foamable composition under conditions effective to form a foam.

9. A process for producing aerosol products comprising the step of adding a composition of any of claims 1 through 3 to a formulation, including active ingredients in an aerosol container, wherein said composition functions as a propellant.
