| titleOfInvention | Method for producing and purifying 2,3,3,3-tetrafluoro-1-propene |
| abstract | The present invention concerns a method for purifying 2,3,3,3-tetrafluoro-1-propene (1234yf) from a first composition comprising 2,3,3,3-tetrafluoro-1-propene and at least one of the compounds chosen from the group consisting of 1,1-difluoroethane (152a), chloropentafluoroethane (115), and trans-1,3,3,3-tetrafluoro-1-propene (1234ze-E) said method comprising the steps consisting 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 said at least one of the compounds chosen from the group consisting of 1,1-difluoroethane (152a) chloropentafluoroethane (115), and trans-1,3,3,3-tetrafluoro-1-propene (1234ze-E); and ii) a stream comprising 2,3,3,3-tetrafluoro-1-propene. The invention also concerns a method for producing and purifying 2,3,3,3-tetrafluoro-1-propene. |
