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 29):
The composition as claimed in  claim 27 , wherein the composition comprises between 75% and 99.99% by weight of 2,3,3,3-tetrafluoro-1-propene, between 0.01% and 25% by weight of trans-1,3,3,3-tetrafluoro-1-propene (1234ze-E) and less than 1% by weight of chloromethane relative to the total weight of the composition.
