An azeotropic composition consisting of 89.2 wt% of 1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluorohexane and 10.8 wt% of methanol and an azeotropic composition consisting of 91.1 wt% of 1,1,1,2,2,3,3,4,4,5,5,6,6- tridecafluorohexane and 8.9 wt% of ethanol. The present invention provides alternative azeotropic solvent compositions which have excellent properties of conventional 1,1,2-trichloro-1,2,2-trifluoroethane and do not deplete the stratospheric ozone layer. |
