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.
