Method For Producing Fluorinated Organic Compounds

Disclosed is a method for producing fluorinated organic compounds, including petnafluoropropenes, which preferably comprises converting at least one compound of formula (I): [in-line-formulae]CFnXmCFaXbCH2X??(I)[/in-line-formulae]to at least one compound of formula (II) [in-line-formulae]CF3CF═CHF??(II)[/in-line-formulae]where each X is independently Cl, I or Br; n is 2 or 3; m is 0 or 1, a is 1 or 2, b is 0 or 1, m+n=3 and a+b=2.

PROCESSES FOR PRODUCING 2,3,3,3-TETRAFLUOROPROPENE, A PROCESS FOR PRODUCING 1-CHLORO-2,2,3,3,3-PENTAFLUOROPROPANE AND AZEOTROPIC COMPOSITIONS OF 1-CHLORO-2,3,3,3-TETRAFLUOROPROPENE WITH HF

A process is disclosed for making CH2=CFCF3. The process involves contacting CH2CICF2CF3 with H2 in a reaction zone in the presence of a catalyst including a catalytically effective amount of palladium supported on a support selected from chromium oxide, fluorinated chromium oxide, chromium fluoride, aluminum oxide, aluminum fluoride and/or fluorinated alumina, to produce CH2=CFCF3. The mole ratio of H2 to the CH2CICF2CF3 fed to the reaction zone is between about 1 :1 and about 4:1. Also disclosed is another process for making CH2=CFCF3 that involves (a) reacting CH2CICF2CF3 with H2 in the presence of a catalytically effective amount of hydrogenation catalyst to form CH3CF2CF3; and (b) dehydrofluorinating CH3CF2CF3 from (a) to form CH2=CFCF3;and another process for making CH2=CFCF3 that involves (1 ) dehydrofluorinating CH2CICF2CF3 in the presence of a catalytically effective amount of dehydrofluorination catalyst to form CHCI=CFCF3; and (2) hydrogenating CHCI=CFCF3 from (1 ) in the presence of a hydrogenation catalyst including a catalytically effective amount of palladium supported on a support selected from chromium oxide, fluorinated chromium oxide, chromium fluoride, aluminum oxide, aluminum fluoride and/or fluorinated alumina to form CH2=CFCF3. Also disclosed is a process for making CH2CICF2CF5. This process involves reacting CH2CIF with CF2=CF2 in a reaction zone in the presence of a catalytically effective amount of an aluminum halide composition having a bulk formula of AICIxBryF3-x-y wherein the average value of x is O to 3, the average value of y is O to 3-x, provided that the average values of x and y are not both O. Also disclosed is an azeotropic composition including CF3CF=CHCI and HF.
