difluoromethane
Also known as Methylene difluoride, HFC-32, CH2F2, methylene fluoride, CF2H2, Freon 32
Difluoromethane, also called HFC-32 or R-32, is an organofluorine compound with the formula CH2F2. It is a colorless gas that is used as a refrigerant. As a hydrofluorocarbon, R-32 is being phased out in the EU. == Synthesis == Difluoromethane is produced by the reaction of dichloromethane and hydrogen fluoride (HF) using SbF5 as a catalyst.
