发明人：WANG LIANG; WANG VIKTORIA
权利人:WANG LIANG; WANG VIKTORIA
摘要:This invention relates to a synthesis of a linear fluorocopolymer having a plurality of pendant phosphorus-containing functional groups. The synthesized phosphorus-containing fluorocopolymer has chain linearity and narrow molecular weight distributions. It has applications as a lubricant additive that provides friction-reduction, anti-wear, and corrosion protection properties.

摘要:Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene which comprises, in one embodiment, reacting a compound of CF 3 X 1 with a compound of CX 2 Hâ•?CHX 3 , wherein X 1 , X 2 , and X 3 are each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CF 3 CHâ•?CHX 3 , wherein X 3 is as described above; and when X 3 is not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoropropene. The process in another embodiment comprises preparing tetrafluoropropene comprising thermally cracking one or more compounds capable of producing a reaction mixture which preferably comprises diflurocarbene radicals and vinylidene fluoride, and converting said reaction mixture into—tetrafluoropropene (1,3,3,3-tetrafluoropropene).
