Abstract (en)
[origin: WO9902615A1] A cleaning and degreasing solvent comprising 1-bromopropane and a dichloropentafluoropropane. Preferably the dichloropentafluoropropane consists essentially of a mixture of 3,3-dichloro-1,1, pentafluoropropane and 1,3-dichloro-1,1,2,2,3-pentafluoropropane. The cleaning and degreasing solvent optionally includes stabilizers and co-solvents to ameliorate the chemical and physical properties of the cleaning solvents. The stabilizer and co-solvents include alcohols, ketones, ethers, acetals, nitroalkanes, epoxides, amines, saturated hydrocarbons, alkenes, alkynes and esters. The solvent composition of the present invention is useful for cleaning a wide variety of articles having metal, cloth, ceramic and plastic surfaces.
