Abstract

Official abstract text for this publication.

The present invention relates to formulated refrigerant systems of 1-chloro-3,3,3-trifluoropropene (R-1233zd) that are sufficiently thermally and chemically stable such that they can be effectively used sans additional stabilizers. The formulations of the present invention are particularly useful compositions for refrigeration, heat transfer and foam blowing.

First claim

Opening claim text (preview).

The invention claimed is: 1. A refrigerant composition comprising the halogenated olefin trans-1-chloro-3,3,3-trifluoropropene, a lubricant selected from the group consisting of mineral oils, alkyl benzene oils and mixtures thereof and water, wherein more than about 99 wt % of said halogenated olefin remains after exposure of said refrigerant composition to metal selected from the group consisting of steel, stainless steel, aluminum, iron, copper, and mixtures thereof at a temperature of 140° C. for 48 hours where in said refrigerant composition does not include a stabilizer for said halogenated olefin. 2. A refrigeration system, air conditioning system, or heat transfer system containing the refrigerant composition of claim 1 . 3. The refrigerant composition of claim 1 , wherein said 1-chloro-3,3,3-trifluoropropene is greater than about 70% trans-1-chloro-3,3,3-trifluoropropene. 4. The refrigerant composition of claim 1 , wherein said 1-chloro-3,3,3-trifluorpropene is consists essentially of trans-1-chloro-3,3,3-trifluoropropene. 5. The refrigerant composition of claim 1 further comprising a component selected from the group consisting of hydrofluorocarbons, hydrochlorofluorocarbons, hydrofluoroolefins, hydrofluorochlorocarbons, hydrocarbons, hydrofluoroethers, fluoroketones, chlorofluorocarbons, trans-1,2-dichloroethylene, carbon dioxide, ammonia, and mixtures thereof. 6.
