Abstract:
The present invention concerns a method for producing for producing and purifying 2,3,3,3-tetrafluoro-1-propene (1234yf) from a first composition comprising 2,3,3,3-tetrafluoro-1-propene and chloromethane (40), said method comprising the steps of: (a) bringing said first composition into contact with at least one organic extractant in order to form a second composition; (b) extractive distillation of said second composition in order to form (i) a third composition comprising said organic extractant and chloromethane (40); and (ii) a stream comprising 2,3,3,3-tetrafluoro-1-propene (1234yf); (c) recovering and separating said third composition, preferably by distillation, in order to form a stream comprising said organic extractant and a stream comprising chloromethane (40).

Claim (Index 26):
A process for producing and purifying 2,3,3,3-tetrafluoro-1-propene, comprising:\n a) fluorinating in the presence of a catalyst a compound of formula (I) CX(Y) 2 \u2014CX(Y) m \u2014CH m XY wherein X and Y independently represent a hydrogen, fluorine or chlorine atom and m=0 or 1 and/or fluorinating in the presence of a catalyst a compound of formula (CX n Y 3-n )CH p X 1-p CH m X 2-m  (II) wherein X is, independently of each other, Cl, F, I or Br; Y is, independently of each other, H, Cl, F, I or Br; n is 1, 2 or 3; and m is 0, 1 or 2; and p is 0 or 1; b) recovering a stream comprising 2,3,3,3-tetrafluoro-1-propene and chloromethane; c) implementing the process as claimed in  claim 15  using the stream recovered in step B).
