Abstract:
Novel surfactants and drying, drycleaning and soil repellency compositions containing such surfactants which utilize such surfactants. The surfactants are fluorine containing quaternary ammonium salts, and the drying, drycleaning and soil repellency compositions contain at least one halocarbon component and at least one of the fluorine containing surfactants. These compositions have the ability to remove water or aqueous films from the surfaces of a broad range of substrates and impart soil repellency to fabrics.
Abstract:
Hydrofluoroalkanes useful as solvents, especially for vapor degreasing and solvent cleaning, are one or many of the above mentioned formulae.
Abstract:
A non-aqueous cleaning process uses an organic solvent for removing soil or surface contamination from contaminated articles such as printed circuit boards which are cleaned by immersion into a sump compartment of a cleaning tank containing the organic cleaning solvent. The organic solvent is preferably a hydrocarbon solvent. The cleaned articles, now coated with the organic cleaning solvent, are then disposed in a rinsing sump containing a fluorocarbon based rinsing solvent having an affinity for the organic cleaning solvent. The organic solvent is thus removed from the articles which are then dried without waste water as in a conventional solvent vapor degreasing solvent process.

Abstract:
The present invention provides a novel lubricating composition comprising a polyoxyalkylene glycol having a cap of a fluorinated alkyl group on at least one end thereof. The composition has a molecular weight between 300 and 3,000, a viscosity of about 5 to about 150 centistokes at 37 DEG C., and a viscosity index of at least 20. The composition is miscible in combination with tetrafluoroethane in the range between -40 DEG C. and at least +20 DEG C. The novel lubricating composition is particularly useful with tetrafluoroethane in refrigeration and air-conditioning applications. As such, the present invention also provides a composition for use in refrigeration and air-conditioning comprising: (a) tetrafluoroethane; and (b) a sufficient amount to provide lubrication of at least one polyoxyalkylene glycol having a cap of fluorinated alkyl group on at least one end thereof. The lubricant has a molecular weight of about 300 to about 3,000, a viscosity of about 5 to about 150 centistokes at 37 DEG C., and a viscosity index of at least 20. The lubricant is miscible in combination with the tetrafluoroethane in the range between about -40 DEG C. and at least about +20 DEG C.
Abstract:
A non-aqueous cleaning process uses an organic solvent for removing soil or surface contamination from contaminated articles such as printed circuit boards which are cleaned by immersion into a sump compartment of a cleaning tank contaning the organic cleaning solvent. The organic solvent is preferably a hydrocarbon solvent. The cleaned articles, now coated with the organic cleaning solvent, are then disposed in a rinsing sump containing a fluorocarbon based rinsing solvent having an affinity for the organic cleaning solvent. The organic solvent is thus removed from the articles which are then dried without waste water as in a conventional solvent vapor degreasing solvent process.
