This invention relates to cleaning compositions comprising unsaturated fluorinated hydrocarbons. The invention further relates to use of said cleaning compositions in methods to clean, degrease, deflux, dewater, and deposit fluorolubricant. The invention further relates to novel unsaturated fluorinated hydrocarbons and their use as cleaning compositions and in the methods listed above.
摘要:
Disclosed is a method for removing residue from a surface comprising: contacting the surface with a composition comprising at least one unsaturated fluorinated hydrocarbon selected from the group consisting of compounds having the formula E- or Z-R1CH=CHR2, wherein R1 and R2 are, independently, C1 to C6 perfluoroalkyl groups, or C1 to C6 hydrofluoroalkyl groups, and recovering the surface from the composition. The fluorinated hydrocarbon is also used as a solvent composition, in a method of depositing a fluorolubricant on a surface and in a process for removing at least a portion of water from the surface of a wetted substrate
摘要:
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.
