Compositions of 1,1,1,2,2,3,5,5,5-nonafluoro-4-trifluoromethylpentane and use thereof for cleaning solid surfaces

摘要

Mixtures of the compound 1,1,1,2,2,3,5,5,5-nonafluoro-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. Binary mixtures of 1,1,1,2,2,3,5,5,5-nonafluoro-4-trifluoromethylpentane with about 5 to 13 weight percent methanol, with about 3 to 11 weight percent ethanol, with about 4 to 12 weight percent isopropanol, with about 52 to 60 weight percent trans-1,2-dichloroethylene, with about 47 to 55 weight percent dichloromethane, with about 1 to 9 weight percent trichloroethane, with about 0.1 to 7 weight percent acetonitrile, and with about 0.1 to 5 weight percent nitromethane, and ternary mixtures of from about 75 to 83 weight percent 1,1,1,2,2,3,5,5,5-nonafluoro-4-trifluoromethylpentane, about 8 to 16 weight percent acetone, and from about 5 to 13 weight percent ethanol, are disclosed as azeotrope or azeotrope-like compositions and are particularly suited for use where solvent recovery and reuse is practiced.
