HCFC-141b (monofluorodichloroethane) is a high-purity liquid widely used in cleaning and solvent fields. Because its damage to the ozone layer is 1/10 of CFC-113, it is designated as an ideal substitute for fully halogenated chlorofluorocarbons. HCFC-141b is a widely used non-perhalogenated chlorofluorocarbon. Although its destructive effect on the ozone layer has been greatly reduced compared to fully halogenated chlorofluorocarbons, it can still cause damage to the ozone layer that is difficult to recover. As a result, its use is gradually being reduced around the world.
