| titleOfInvention | Method for producing tetrafluoroethylene |
| abstract | There is provided a process for recoveringntetrafluoroethylene wherein an amount of energy required tonobtain TFE is reduced. n In the process for producing a TFE mixture as annintended mixture which contains TFE at a highernconcentration from a raw material mixture (10) whichncontains TFE, a component of which boiling point is lowernthan that of TFE and a component of which boiling point isnhigher than that of TFE,n (1) the raw material is subjected to a preliminaryndistillation treatment (12) so as to obtain (a) a first fractionn(15) which contains at least a portion of the component ofnwhich boiling point is higher than that of TFE and (b) ansecond fraction (14) as the balance which contains TFE andnthe component of which boiling point is lower than that ofnTFE, and then (2) the second fraction is subjected to a mainndistillation treatment (16) so as to obtain (c) a third faction (20) formed by distilling off the component of which boilingnpoint is lower than that of TFE, and (d) a fourth fractionn(18) as the intended mixture being the balance whichncontains TFE. |
