Patent ID: 8232235

Claim:
A composition comprising a blend of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, trans-1,2-dichloroethylene, and a third component, wherein the third component is selected from: (i) methanol, wherein the composition, when fractionally distilled, forms a distillate fraction that is an azeotrope consisting essentially of about 18.6 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, 73.0 weight percent of trans-1,2-dichloroethylene, and 8.4 weight percent of methanol, the distillate fraction boiling at about 40° C. at ambient pressure; (ii) ethanol, wherein the composition, when fractionally distilled, forms a distillate fraction that is an azeotrope consisting essentially of about 20.2 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, 75.3 weight percent of trans-1,2-dichloroethylene, and 4.5 weight percent of ethanol, the distillate fraction boiling at about 45° C. at ambient pressure; (iii) isopropanol, wherein the composition, when fractionally distilled, forms a distillate fraction that is an azeotrope consisting essentially of about 20.5 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, 77.3 weight percent of trans-1,2-dichloroethylene, and 2.2 weight percent of isopropanol, the distillate fraction boiling at about 45° C. at ambient pressure; (iv) t-butanol, wherein the composition, when fractionally distilled, forms a distillate fraction that is an azeotrope consisting essentially of about 21.0 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, 77.8 weight percent of trans-1,2-dichloroethylene and 1.2 weight percent of t-butanol, the distillate fraction boiling at about 46° C. at ambient pressure; and (v) 1-propanol, wherein the composition, when fractionally distilled, forms a distillate fraction that is an azeotrope consisting essentially of 24.5 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane, 74.9 weight percent of trans-1,2-dichloroethylene and 0.6 weight percent of 1-propanol, the distillate fraction boiling at about 46° C. at ambient pressure.
