| titleOfInvention | Heat transfer compositions containing as stabilizer either a zinc dialkyldithiophosphate or a metal salt of an alkylarylsulfonic acid |
| abstract | ABSTRACT OF THE DISCLOSURE: The invention relates to heat, transfer compositions for absorption heat pumps, which consist of mixtures of chlorofluorohydrocarbons and solvents, the said mixtures comprising a heat transfer chlorofluorohydrocarbon having from 1 to 3 carbon atoms and being substituted by at least one hydrogen atom, an amide of the type comprising at least one bond or a glycolether compound as a solvent, and a sufficient quantity of a stabilizer to inhibit the decomposition of the chlorofluorohydrocarbon and solvents at temperatures ranging up to 180°C, said stabilizer being selected from the group consisting of zinc dialkyl-dithiophosphates of formula: in which R' and R", which are identical or different, represent alkyl, aryl, alkylaryl or arylalkyl radicals containing at least 3 carbon atoms, preferably at least 6 carbon atoms; and metal salts of alkylarylsulfonic acids of the formula: (RmAr SO3)nM in which R is an alkyl group having from 1 to 15 carbon atoms, Ar is an aryl group, M is a metal ion, preferably zinc on an alkaline earth metal, m is an integer from 1 to 3 and n is an integer which corresponds to the valency of the metal, with the proviso that when the stabilizer is a metal salt of an alkylarylsulfonic acid, the solvent is not a N-methyl-pyrrolidone. These compositions are stable at temperatures ranging up to 180°C. |
