F 152a is an important organic fluorine industrial product. It is a colorless gas with slight odor, insoluble in water, soluble in alcohol and ether solvents, and its boiling point is -24.7℃. It is a low toxic chemical, which has anesthetic effect and flammability at high content, and will react violently when it meets strong oxidant. Difluoroethane is an important raw material for preparing vinylidene fluoride and vinylidene fluoride, and can also be used as refrigerant, aircraft propellant, aerosol propellant and refrigerant. It is a refrigerant, colorless and tasteless at room temperature. The boiling point of gas is flammable and explosive.
