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 solvent/cleaner composition consisting of the hydrochloroolefin 1233zd and an alcohol selected from the group consisting of methanol, ethanol and iso-propanol wherein the hydrochlorofluorolefin 1233zd comprises about 70 wt % or more the trans steroisomer of hydrochloroolefin 1233zd, wherein said solvent/cleaner composition has a Kauri-butanol value of greater than about 15. 2. The solvent/cleaner composition of claim 1 wherein said hydrochlorofluoroolefin 1233zd comprises about 90 wt % or more said trans stereoisomer. 3. The solvent/cleaner composition of claim 1 wherein said hydrochlorofluoroolefin 1233zd comprises about 97 wt % or more said trans stereoisomer. 4. The solvent/cleaner composition of claim 1 , further comprising hydrofluorocarbons, hydrofluoroolefins, hydrocarbons, ethers, hydrofluoroethers, esters, ketones, 1,2-transdichloroethylene and mixtures thereof. 5. The solvent/cleaner composition of claim 4 wherein said ester is selected from the group consisting of methyl formate, methyl acetate, ethyl formate and ethyl acetate. 6. The solvent/cleaner composition of claim 1 having a Kauri-butanol value of eater than about 20. 7. A method of removing contaminates from a surface comprising contact said surface with a liquid and/or vapor comprising the hydrochlorofluoroolefin 1233zd and an alcohol wherein said hydrochlorofluoroolefin 1233zd comprises 70 wt % or more the trans stereoisomer of hydrochlorofluoroolefin 1233zd. 8. The method of claim 7 wherein said liquid and/or vapor comprises about 90 wt % or more said trans stereoisomer. 9. The method of claim 7 wherein said liquid and/or vapor comprises about 97 wt % or more said trans stereoisomer. 10. The method of claim 7 wherein said alcohol is selected from the group consisting of methanol ethanol and iso-propanol. 11. The method of claim 7 wherein said liquid and/or vapor further comprising hydrofluorocarbons, hydrofluoroolefins, hydrocarbons, ethers, hydrofluoroethers, esters, ketones, and mixtures thereof. 12. The method of claim 7 wherein said ester is selected from the group consisting of methyl formate, methyl acetate, ethyl formate and ethyl acetate. 13. The method of claim 7 wherein said liquid and/or vapor has a Kauri-butanol value of greater than about 15. 14. The method of claim 7 wherein said liquid and/or vapor has a Kauri-butanol value of greater than about 20.
