Compositions including 1,1,1,3,3-pentafluorobutane and at least one surface-active agent chosen from hydrophobic organic surface-active agents of the amine, carboxylic acid diester and phosphoric acid ester types, which can be employed for removing water from a solid surface.

Compositions including 1,1,1,3,3-pentafluorobutane and process for removing water from a solid surface

Refrigerant of 1,1-difluoroethylene

Hydrofluorocarbon-containing compositions and method for removing water

Compositions based on 1,1-dichloro-1-fluoroethane and a surfactant comprising at least one imidazoline, which are usable for removing water from a solid surface.

Compositions comprising 1,1-dichloro-1-fluoroethane and process for the

Hydrofluoroalkanes are effectively stabilized against degradation caused by Lewis acids by addition of 0.001 to less than 0.1% by weight of at least one C.sub.1 -C.sub.2 alcohol and/or of 0.001% to 0.5% of a C.sub.5 -C.sub.6 unsaturated hydrocarbon.

Process for stabilizing a hydrofluoroalkane and compositions comprising

The invention relates to compositions comprising 1,1,1,3,3-pentafluorobutane, 1,2-dichloroethylene and optionally a C1-C3 alkanol. These compositions can be used especially as solvents for cleaning and defluxing electronic components and for degreasing metals.

Compositions comprising pentafluorobutane and trans-1,2-dichloroethylene

The invention relates to compositions containing difluoromethoxy-2,2,2-trifluoroethane and an alcohol. These compositions can be used especially as solvent for cleaning electronic components and for degreasing metals.

Compositions containing a fluorinated ether and use of these compositions

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

Compositions consisting essentially of 1,1-dichloro-1-fluoroethane and at least one stabilizing agent chosen from epoxides and hydrocarbons substituted by a nitro group. These compositions can especially be used as cleaning agent and as blowing agent for polyurethane foams.

Stabilized 1,1-dichloro-1-fluoroethane, premixtures intended for the

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

The invention relates to azeotropic and pseudoazeotropic compositions comprising difluoromethoxy-2,2,2-trifluoroethane with 2,2-dichloro-1,1,1-trifluoroethane or with 1,1-dichloro-1-fluoroethane. These compositions can be employed as solvents, especially for cleaning electronic components and for degreasing metals, as blowing agents, especially for the preparation of polyurethane foams, or as refrigerants.

Compositions comprising a fluoro ether and use of these compositions

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.
