Patent ID: 7767635

Claim:
An azeotrope-like composition comprising a blend of (a) 1-methoxy-2-propanol; and (b) a hydrofluoroether, wherein the blend is selected from: (i) a blend consisting essentially of greater than 0 to about 69 weight percent of 1-methoxy-2-propanol and less than 100 to about 31 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-trifluoromethyl-pentane that boil below about 97.7° C. at about 101 kilopascals (kPa); (ii) a blend consisting essentially of about 17 to less than 100 weight percent of 1-methoxy-2-propanol and about 83 to greater than 0 weight percent of 1,1,1,2,3,3-hexafluoro-4-(1,1,2,3,3,3-hexafluoro-propoxy)-pentane that boil below about 119.7° C. at about 101 kPa; or (iii) a blend consisting essentially of greater than 0 to about 4.7 weight percent of 1-methoxy-2-propanol and less than 100 to about 95.3 weight percent of 1-ethoxy-nonafluorobutane that boil below about 75.96° C. at about 101 kPa.
