Abstract
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.

Composition comprising a fluorinated base, diacetone alcohol, and dimethyl sulfoxide and/or secondary butanol.
Method for treating solid surfaces, performed in a machine comprising a cleaning tank (2) and a rinsing tank (8), characterized in that the cleaning tank (2) is filled with a composition comprising a first fluorinated base, diacetone alcohol, and dimethyl sulfoxide and/or secondary butanol and the rinsing tank (8) is filled with a pure second fluorinated base, said second fluorinated base the same as or different from said first fluorinated base in the cleaning tank (2).
