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.
