Cleaning compositions containing selected hydrogen-containing fluorochlorohydrocarbons, selected surface-active agents, and optional amounts of water and/or ammonia.

Composition with hydrogen-containing fluorochlorohydrocarbons

Fluorochlorohydrocarbon-free cleaning compositions composed of from 80 to 99.5 percent by weight of an alcohol or partially fluorinated alcohol having 2 to 4 carbon atoms and 0.5 to 10 percent by weight of at least one surface-active agent selected from ammonium salts of alkyl benzene sulfonates and mixtures of fatty acid alkanolamides and alkyl phenol polyglycol ethers, and 0 to 10 percent by weight of deionized water.

Fluorochlorohydrocarbon-free cleaning compositions

Improved cleaning compositions are disclosed based on fluorochlorohydrocarbons, alkanols and at least one ester selected from the group consisting of methyl propionate, ethyl propionate and ethyl acetate. The compositions may optionally contain additional additives and are highly suitable for industrial cleaning processes or for vapor degreasing, for example, particularly for removing resin soldering fluxes containing high amounts of activator.

Cleaning compositions (containing fluorochlorocarbon, C.sub.1 to C.sub.4

Cleaning compositions

Compositions composed of fluorochlorohydrocarbons selected from the group consisting of the dichlorotrifluoroethanes in admixture with lower alkanols. The compositions are especially suitable for use as cleaning compositions, particularly for removing organic resin fluxes or flux residues from printed circuit boards.

Cleaning compositions comprising dichlorotrifluoroethanes and alkanols

Liquid compositions having release effective properties, which contain dichloromonofluoroethanes as a solvent and at least one agent with release effective properties, and the use of these compositions and a process for their preparation are described.

Dichloromonofluoroethane compositions

Liquid compositions having properties of activity as release agents are described, which contain dichlorotrifluoroethane as a solvent and at least one agent with release effective properties, as well as the use of these compositions and a process for the preparation thereof.

Dichlorotrifluoroethane-containing mixtures

New mixtures comprising difluorotetrachloroethane and petroleum ethers are described for use, inter alia, as solvents, particularly for waxes.

Difluorotetrachloroethane mixtures and their use in removing waxes

A process is disclosed for reacting hydrogen fluoride with a fatty acid ester having a melting point less than than 60.degree. C. The resulting products and various applications for them as lubricants, lubricant additives and pharmaceutical carriers are also described.

Process for producing novel products by hydrogen fluoride with esters of

A process for chip forming, cutting or abrasive treatment of metals using a fluorochlorohydrocarbon containing cooling lubricant is described. The lubricant contains esters of long chain carboxylic acids and monoalcohols having a total of 34 to 50 carbon atoms or derivatives of said esters. Also disclosed is a cooling lubricant to be used in the process and a process for the preparation of such a cooling lubricant.
