| titleOfInvention | Method for producing and purifying 2,3,3,3-tetrafluoro-1-propene |
| abstract | The invention relates to a method for purifying 2,3,3,3-tetrafluoro-1-propene (1234yf) using a first composition comprising 2,3,3,3-tetrafluoro-1-propene, 1,1,1,2,2-pentafluoropropane (245cb) 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 a third composition comprising said organic extraction agent and trans-1,3,3,3-tetrafluoro-I-propene (I234ze-E), and a stream comprising the 2,3,3,3-tetrafluoro-I-propene and the 1,1,1,2,2-pentafluoropropane (245cb); and (c) recovery and separation of said third composition in order to form a stream comprising said organic extraction agent and a stream comprising the trans-1,3,3,3-tetrafluoro-I-propene (1234ze-E). The invention also relates to a method for producing 2,3,3,3-tetrafluoro-I-propene. |
