PURPOSE:The titled composition, capable of reducing the decomposition of Flon and deterioration of oils, and preventing the corrosion of an apparatus and the reduction in capacity of a compressor and the deterioration of the lubricating characteristics, and comprising Flon and a specific amount of a specified dialkylpentaerythritol diphosphite. CONSTITUTION:A composition for a heating medium comprising 100pts.wt. Flon , preferably a methane type chlorofluorinated alkane, e.g. trichlorofluoromethane (Flon 11 ) or an ethane type chlorofluorinated alkane, e.g. dichlorotetrafluoroethane (Flon 114), and 0.01-5pts.wt. dialkylpentaerythritol diphosphte having a 1-20C alkyl group. USE:Useful for a power medium, e.g. a Flon turbine. |
