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.

Difluoromethoxy-2, 2, 2-trifluoroethane compositions and methods of use

Difluoromethoxy-2,2,2-trifluoroethane compositions and methods of use

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.

Compositions comprising difluoromethoxy-2,2,2-trifluoroethane

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.

Compositions comprising chlorine-free, optionally hydrogen-containing

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.

Compositions containing 1-chloro-2,2,2-trifluoroethyl defluoromethyl

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.

Virtually constant boiling point compositions based on isoflurane

Compositions suitable for use in cleaning processes formed of hydrogen-containing fluorochlorohydrocarbons selected from the group of consisting of tetrachloromonofluoroethanes, trichlorodifluoroethanes, dichlorotrifluoroethanes, dichloromonofluoroethanes and dichloropentafluoropropanes or a mixture one or more of these hydrogen-containing fluorochlorohydrocarbons in admixture with partially fluorinated alkanols containing two to four carbon atoms.

Cleaning compositions, formed of hydrogen-containing

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.

1-chloro-2,2,2-trifluoroethyl difluoromethyl ether compositions for

Cleaning compositions formed of hydrogen-containing

Azeotropic and azeotrope-like compositions composed of dichloropentafluoropropanes and acetone are described which are suitable for use in cleaning processes and in printing and copying processes for fixing toner based on polystyrene.

Dichloropentafluoropropanes and acetone compositions

Compositions are described based on hydrogen-containing fluorochlorohydrocarbons selected from the dichloropentafluoropropanes which contain defined amounts of specific surface-active substances selected from the group consisting of straight-chain alkylamines having 9 to 12 carbon atoms, straight chain carboxylic acids having 9 to 12 carbons atoms, branched alkylamines having 8 to 12 carbon atoms, branched carboxylic acids having 8 to 12 carbon atoms, alkyl phosphates, aryl phosphates, mixed alkyl/aryl phosphates, salts of the foregoing alkylamines with the foregoing carboxylic acids, and salts of straight-chain or branched C8- to C12-alkylamines with alkyl, aryl or mixed alkyl/aryl mono- or diesters of phosphoric acid. A process for using these compositions to remove water from surfaces of a wide variety of articles and from a wide variety of materials is also described.
