PROCESS FOR THE CO-PRODUCTION OF OF 2,3,3,3-TETRAFLUOROPROPENE AND 1,3,3,3-TETRAFLUOROPROPENE

The present invention provides a method of producing 2,3,3,3-tetrafluoropropene (HFO- 1234yf), wherein the method comprises two or more reaction steps, at least one of said reaction steps comprising the production of 1,3,3,3-tetrafluoropropene (HFO-1234ze) and/or one or more HFO-1234ze precursors from one or more HFO-1234yf precursors, wherein at least a portion of the HFO-1234ze is recovered.

PROCESS FOR SYNTHESIS OF FLUORINATED OLEFINS

Disclosed is a process for the synthesis of fluorinated olefins, and in particularly preferred embodiments tetrafluorinated olefins having F on an unsaturated, non-terminal carbon, such as 2,3,3,3-tetrafluoropropene. The preferred processes of the present invention in accordance with one embodiment generally comprise: (a) reacting a compound of formula (I) [in-line-formulae]X1X2??(I)[/in-line-formulae] with a compound of formula (II) [in-line-formulae]CX1X2X3CX1═CX1X2??(II)[/in-line-formulae] to produce a reaction product comprising a compound of formula (III) [in-line-formulae]CF3CHX1CH2X2??(III), and[/in-line-formulae](b) exposing said compound of formula (III) to reaction conditions effective to convert said compound of formula (III) to a compound of formula (IV) [in-line-formulae]CF3CZ=CH2??(IV)[/in-line-formulae] wherein X1, X2, and X3 are each independently selected from the group consisting of hydrogen, chlorine, bromine, fluorine and iodine, provided that X1 and X2 in formula (I) are not both hydrogen and Z is Cl, I, Br, or F.

PROCESSES FOR THE PRODUCTION OF FLUOROPROPANES AND HALOPROPENES

A process is disclosed for making CF3CF2CH3, CF3CF=CH2 and/or CF3CCI=CH2. The process involves reacting at least one starting material selected from the group consisting of halopropanes of the formula CX3CH2CH2X, halopropenes of the formula CX3CH=CH2 and halopropenes of the formula CX2=CHCH2X, wherein each X is independently F or Cl, with HF and CI2 in a reaction zone to produce a product mixture comprising HF, HCI, CF3CF2CH3, CF3CF=CH2, and CFsCCI=CH2; and recovering the CF3CF2CH3, CF3CF=CH2 and/or CFsCCI=CH2 from the product mixture. Also disclosed is a process for making CF3CH2CHF2, CFsCH=CHF, and/or CFaCH=CHCI. This process involves reacting at least one starting material selected from the group consisting of halopropenes of the formula CX3CH=CH2 and halopropenes of the formula CX2=CHCH2X, wherein each X is independently F or Cl, with HF and CI2 in a reaction zone to produce a product mixture comprising HF, HCI, CF3CH2CHF2, CFsCH=CHF and CF3CH=CHCI; and recovering the CF3CH2CHF2, CFsCH=CHF, and/or CF3CH=CHCI from the product mixture. The molar ratio of HF to the total amount of starting materials fed to the reaction zone for both of these processes is at least stoichiometric, and the molar ratio of Cl2 to total amount of starting material fed to the reaction zone for both of these processes is 2:1 or less.
