Abstract
Official abstract text for this publication.
The present invention relates to solvent/cleaner and heat transfer fluid compositions comprising at least one hydrochlorofluoroolefin (HCFO), 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), particularly the trans-isomer. The HCFO of the present invention can be used in combination with co-agents including, hydrofluorocarbons (HFCs), hydrofluoroolefins (HFOs), hydrocarbons, ethers including hydrofluoroethers (HFEs), esters, ketones, alcohols, 1,2-transdichloroethylene and mixtures thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat transfer fluid composition comprising hydrochlorofluoroolefin 1233zd wherein about 99 wt % or more of the hydrochlorofluoroolefin is the trans stereoisomer of the hydrochlorofluoroolefin 1233zd. 2. The heat transfer fluid composition of claim 1 , further comprising hydrofluorocarbons, hydrofluoroolefins, hydrocarbons, ethers, hydrofluoroethers, esters, ketones, alcohols, 1,2-transdichloroethylene and mixtures thereof. 3. A process for producing refrigeration comprising compressing a refrigerant in a compressor, and evaporating the refrigerant in the vicinity of a body to be cooled, wherein said refrigerant comprises the hydrochlorofluoroolefin 1233zd wherein about 99 wt % or more of the hydrochlorofluoroolefin is the trans stereoisomer of the hydrochlorofluoroolefin 1233zd. 4. The process of claim 3 wherein said refrigerant further comprises hydrofluorocarbons, hydrofluoroolefins, hydrocarbons, ethers, hydrofluoroethers, esters, ketones, alcohols, 1,2-transdichloroethylene and mixtures thereof.
