The present invention concerns the field of fluorinated hydrocarbons and relates to novel compositions containing fluorinated hydrocarbons and oxygenated solvents. More particularly, the compositions comprise a fluorinated base, diacetone alcohol (DAA), and DMSO and/or secondary butanol. These novel compositions can be used in particular in all solvent applications of HCFC 141b (hydrochlorofluorocarbon 141b), in particular in various operations for treating solid surfaces, such as the cleaning, degreasing, defluxing or drying of solid surfaces.

The invention claimed is: 1. Composition comprising a fluorinated base selected from the group consisting of hydrofluorocarbons, hydrofluoro ethers and mixtures thereof, diacetone alcohol, and dimethyl sulfoxide and optionally secondary butanol. 2. Composition according to claim 1, comprising from 1 to 88% by weight of fluorinated base, from 5 to 94% by weight of diacetone alcohol, and from 5 to 70% by weight of dimethyl sulfoxide and optionally secondary butanol. 3. Composition according to claim 1, comprising from 5 to 80% of fluorinated base, from 15 to 85% of diacetone alcohol and from 5 to 50% of dimethyl sulfoxide and optionally secondary butanol. 4. Composition according to claim 1 wherein said fluorinated base comprises one or more halogenated compounds having a surface tension of less than 30 mN/m and a zero ozone degradation potential. 5. Composition according to claim 1 wherein said composition further comprises trans-1,2-dichloroethylene. 6.
