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 polyol B-side composition comprising polyol, catalyst, surfactant and a blowing agent composition comprising the halogenated olefin 1-chloro-3,3,3-trifluoropropene and less than about 2% of impurities selected from the group consisting of HFO-1234ze, HFC-245fa and mixtures thereof wherein more than about 99 wt % of said halogenated olefin remains after exposure of said composition to temperature of 100° C. for 24 hours. 2. The polyol B-side composition of claim 1 wherein said 1-chloro-3,3,3-trifluoropropene is predominantly trans-1-chloro-3,3,3-trifluoropropene. 3. The polyol B-side 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 polyol B-side composition of claim 1 wherein said 1-chloro-3,3,3-trifluoropropene is consists essentially of trans-1-chloro-3,3,3-trifluoropropene. 5. The polyol B-side 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.
