    摘要: 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.
