The invention relates to a method for producing and purifying 2,3,3,3-tetrafluoro-1-propene using a first composition comprising 2,3,3,3-tetrafluoro-1-propene, 3,3,3-trifluoropropene (1243zf), and trans-1,3,3,3-tetrafluoro-1-propene (1234ze-E), said method comprising the steps of: (a) bringing said first composition into contact with at least one organic extraction agent 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 extraction agent, 3,3,3-trifluoropropene (1243zf), and trans-1,3,3,3-tetrafluoro-1-propene (1234ze-E), and (ii) a stream comprising the 2,3,3,3-tetrafluoro-1-propene; and (c) recovery and separation of said third composition in order to form a stream comprising said organic extraction agent and a stream comprising 3,3,3-trifluoropropene (1243zf) and trans-1,3,3,3-tetra-fluoro-1-propene (1234ze-E).
