由于氟烷烃具有不燃性和沸点较低的特性,在20世纪30年代初,这类化合物开始作为冷冻剂。从此,有机氟化合物即从实验室一跃而为大量生产的工业品。50年代后,气溶胶喷射剂和气溶胶杀虫剂相继问世,又使氟烷烃扩大了生产规模。例如,1975年美国年产氟烷烃已达80亿美元,约有100万工人参加生产。目前,此类化合物在工业上已广泛用作冷冻剂、发泡剂、金属洗涤剂、灭火剂、含氟高分子原料、有机溶剂等;农业上用作气溶胶杀虫剂;医学上用作治疗的气
Due to the non-flammable and low boiling point properties of the fluoroalkanes, these compounds started to be used as refrigerants in the early 1930s. Since then, organic fluorine compounds that jumped from the laboratory for the mass production of industrial products. Since the 1950s, aerosol propellants and aerosol insecticides have been introduced one after another, which in turn has increased the production scale of HFA. For example, in the United States in 1975, the annual output of HFCs reached US $ 8 billion and about 1 million workers took part in the production. Currently, these compounds have been widely used in industry as refrigerants, foaming agents, metal detergents, fire extinguishing agents, fluorine-containing polymer raw materials, organic solvents, etc .; agriculture as an aerosol insecticide; Treatment of the gas
