Abstract:
An azeotrope-like composition comprising:(a) 3-ethoxy-perfluoro(2-methyl hexane); and (b) organic solvent; â€ƒwherein said composition is selected from the group consisting of: (i) compositions consisting essentially of about 86 to about 41 weight percent of 3-ethoxy-perfluoro(2-methylhexane) and about 14 to about 59 weight percent of n-octane that boil at about 115.5 to about 116.5Â° C. at about 760 torr; (ii) compositions consisting essentially of about 79 to about 32 weight percent of 3-ethoxy-perfluoro(2-methylhexane) and about 21 to about 68 weight percent of 1,3-dimethylcyclohexane that boil at about 112.0 to about 113.0Â° C. at about 760 torr; and (iii) compositions consisting essentially of about 99.9 to about 89 weight percent of 3-ethoxy-perfluoro(2-methylhexane) and about 0.1 to about 11 weight percent of ISOPARâ„¢ G (a mixture of high purity C10-C11 isoparaffinic hydrocarbons) that boil at about 129.7 to about 130.1Â° C. at about 760 torr.
