REFRIGERANT 22
((Difluorochloromethane, R22, Freon 22)Also Known As: Chlorodifluoromethane, F 22, R-22, 4-01-00-00032 (Beilstein Handbook Reference), Algeon 22, Algofrene 22, Algofrene type 6, Arcton 22, Arcton 4, BRN 1731036, CFC 22, Daiflon 22, Difluorochloromethane, Difluoromonochloromethane, Dymel 22, Electro-CF 22, Eskimon 22, FC 22, Flugene 22, Fluorocarbon-22, Forane 22, Forane 22 B, Freon 22, Frigen, Frigen 22, Genetron 22, Haltron 22, HFA-22, HSDB 143, Isceon 22, Isotron 22, Khladon 22, Monochlorodifluoromethane, Racon 22, Refrigerant R 22, Ucon 22.
Refrigerant 22 (Freon 22, R22) is a colorless gas with weak specific odor. It is use for obtaining temperature up to minus 40°С at first stage and temperature up to minus 60°С at second stage in refrigerating units and in household and industrial air-conditioners. It is also use as a mixture component, a pore-forming agent for producing plastic foam and for obtaining fluoro-monomers and other fluoro-organic substances.
Refrigerant 22 (Freon 22, R22) is a non-combustible and non-explosive gas. Self-ignition temperature is above 700°C. In case of contact with flame or hot surfaces, it decomposes producing highly toxic products. It reacts with chlorine and bromine at temperature of 400-600°C in the gas phase or at catalyst. It is allow for production and usage until 2030. Substitutes for Halocarbon 22: R404a, R407a, R407c, R410a, R507, Isceon 59, R290 and R717.
Refrigerant 22 (Freon 22, R22) is packed in steel cylinders working under pressure. Filling (charging, pumping) factor not more than 1kg on 1 dm3 of cylinder capacity. The product is stored in warehouse, under a canopy or in open air avoiding direct sunlight.
All types of carriage in compliance with hazardous goods rules transport R22.
Chemical formula - CF2CIH.
