Abstract: Refrigerants comprising 1,1-difluoroethylene and one or more hydrofluoroalkanes, in particular difluoromethane (R-32), trifluoromethane (R-23), 1,1-difluoroethane (R-152a), 1,1,1-trifluoroethane (R-143a), 1,1,1,2-tetrafluoroethane (R-134a) and/or pentafluoroethane (R-125).

Abstract: The present invention relates to new uses of difluoromethoxy-2,2,2-trifluoroethane (E245) or of compositions which contain difluoromethoxy-2,2,2-trifluoroethane together with a further solvent (cosolvent). The invention furthermore relates to new compositions of E245 as a mixture with some of these solvents. A preferred process of use is fixing toner applied to a recording material in the fixing device of a printing or copying apparatus by means of a fixing vapor composed of difluoromethoxy-2,2,2-trifluoroethane (E245) alone or in admixture with a cosolvent.

Abstract: Liquid or pasty compositions having release-effective properties, which contain difluoromethoxy-2,2,2-trifluoroethane (E245), either alone or admixed with additional solvents, and at least one agent having release-effective properties, and also the use of these compositions and a method for their preparation.

Abstract: Compositions which are liquefied under pressure, are suitable as release agents and comprise a fluorocarbon (FC) from the group comprising R134a, R143a, R125, R32, R143, R134, R23, R152a, R14 and R116 and an agent having a releasing action and, if appropriate, other additives, customary for release agents are described; the compositions with the hydrogen-containing fluorocarbons (HFC) mentioned are preferred here. The use of the compositions as release agents and a process for their preparation are likewise described.

Abstract: Liquid compositions useful as release agents or cooling lubricants containing 1-chloro-2,2,2-trifluoroethyl difluoromethyl ether and an agent having a lubricant and/or release action and optionally further conventional additives for release agents or cooling lubricants, the use of such compositions as release agents or cooling lubricants, and a process for preparing such compositions.

Abstract: The invention relates to azeotropic and pseudoazeotropic compositions containing isoflurane with a lower alcohol or an ester. These compositions can be used in particular as a solvent for cleaning electronic components and for degreasing metals.

Abstract: A composition composed of 1-chloro-2,2,2-trifluoroethyl difluoromethyl ether and at least one surface-active substance and the use of such a composition for removing water from surfaces of objects of diverse material and type are described.
