    摘要: The present invention involves methods for isomerization of 1234zc. Also provided are methods for managing 1,1,3,3-tetrafluoropropene produced as a byproduct in a process for synthesizing trans-1,3,3,3-tetrafluoropropene from 245fa, wherein 1234zc is converted into trans/cis-1234ze with the help of a catalyst in the absence of HF and in an isomerization reactor, or is converted into 1234zc and/or 245fa with the help of a catalyst in the presence of HF in a separate reactor or preferably in the same reactor of 245fa dehydrofluorination.

    摘要: Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF═CH2 (1234yf). In certain preferred embodiments the processes comprise first exposing a compound of Formula (IA) C(X)2═CClC(X)3  (IA) where each X is independently F, Cl or H, preferably CCl2═CClCH2Cl, to one or more sets of reaction conditions, but preferably a substantially single set of reaction conditions, effective to produce at least one chlorofluoropropane, preferably in accordance with Formula (IB): CF3CClX′C(X′)3  Formula (IB) where each X′ is independently F, Cl or H, and then exposing the compound of Formula (IB) to one or more sets of reaction conditions, but preferably a substantially single set of reaction conditions, effective to produce a compound of Formula (II) CF3CF═CHZ  (II) where Z is H, F, Cl, I or Br.
