Briton R22 Refrigerant Gas

Briton Refrigerant R22 – Chlorodifluoromethane

Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22, or (CH ClF2). It is commonly used as a propellant and refrigerant. These applications are being phased out in developed countries due to the compound’s ozone depletion potential (ODP) and high global warming potential (GWP), although global use of R-22 continues to increase because of high demand in developing countries. R-22 is a versatile intermediate in industrial organofluorine chemistry, e.g. as a precursor to tetrafluoroethylene. R-22 cylinders are colored light green.

R-22 is prepared from chloroform:

HCCl3 + 2 HF → HCF2Cl + 2 HCl
