Abstract
627,936. Refrigerating. GENERAL MOTORS CORPORATION. Aug. 21, 1947, No. 23180. Convention date, Sept. 21, 1946. [Class 29] A working fluid for refrigerating systems comprises as a major constituent a halogenated aliphatic hydrocarbon and a lubricant, and as a minor constituent an organic oxide in which an oxygen atom is linked to two adjacent carbon atoms acting as a corrosion inhibitor. A preferred refrigerant is difluorodichloromethane and a preferred oxide propylene oxide 1.2 in an amount ranging from ¢ per cent to 5 per cent of the refrigerant. Other oxides suitable which may include phenyl groups are mentioned. An alcohol may be added as an antifreeze agent.
