ABSTRACT:
Mixtures of the two fluorocarbon compounds 1,1,2,2,3,5,5,5-nonafluoro-4-trifluoromethylpentane and 1,1,1,2,2,5,5,5-octafluoro-4-trifluoromethylpentane with alcohols, ethers, esters, ketones, nitrogen-containing organic compounds, and halogenated hydrocarbons are disclosed; as is a process for cleaning a solid surface which comprises treating the surface with said mixtures. Ternary mixtures of about 88 to 96 weight percent total of said two fluorocarbon compounds with methanol (including at least about 11 weight percent 1,1,1,2,2,3,5,5,5-nonafluoro-4-trifluoromethylpentane and at least about 13 weight percent 1,1,1,2,2,5,5,5-octafluoro-4-trifluoromethylpentane) and with ethanol (including at least about 28 weight percent 1,1,1,2,2,3,5,5,5-nonafluoro-4-triluoformethylpentane and at least about 16 weight percent 1,1,1,2,2,5,5,5-octafluoro-4-trifluoromethyl-pentane) are disclosed as quasiazeotrope compositions that are useful where recovery and reuse of solvents is practiced.
