| titleOfInvention | PROCESS FOR PRODUCING AND PURIFYING 2,3,3,3-TETRAFLUORO-1-PROPENE |
| abstract | The present invention relates to a process 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 one of the compounds selected from the group consisting of 1,1-difluoroethane (152a), chloropentafluoroethane (115), trans-1,3,3,3-tetrafluoro-1-propene (1234ze-E), said process comprising the steps of a) contacting said first composition with at least one organic extractant to form a second composition; b) extractively distilling said second composition to form i) a third composition comprising said organic extractant and said at least one of the compounds selected from the group consisting of 1,1-difluoroethane (152a), chloropentafluoroethane (115), 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 relates to a method for producing and purifying 2,3,3,3-tetrafluoro-1-propene. |
