数据库记载的用途

Used in the production of polyvinylidene fluoride polymers and elastomers; [HSDB]
Plastic Composites Manufacturing [Category: Industry]
Manufacture of polymers and copolymers; chemical intermediate
Used for the mfg of poly(vinylidene fluoride) and for copolymerization with many fluorinated monomers. One commercially significant use is the mfg of high performance fluoroelastomers that include copolymers of 1,1-difluorothene with hexafluoropropylene (HFP) or chlorotrifluoroethylene (CTFE) and terpolymers with HFP and tetrafluoroethylene
Currently, three basic methods are used for the commercial production: (1) dechlorination of 1,2-dichloro-1,1-difluoroethane in the gas phase and on a metal catalyst, (2) dechlorination of 1-chloro-1,1-difluoroethane, and (3) dehydrofluorination of 1,1,1-trifluoroethane.
Thermal elimination of HCl from 1-chloro-1,1-difluoroethane is the principal industrial route...dehydrohalogenation of 1-bromo-1,1-difluoroethane or 1,1,1-trifluoroethane, or dehalogenation of 1,2-dichloro-1,1-difluoroethane are alternative routes; it can also be continuously prepared by the pyrolysis of trifluoromethane in the presence of a catalyst and either methane or ethylene.
