| titleOfInvention | Method for purifying reaction products resulting from hydrogenation of EDDN or EDMN |
| abstract | Separation of reaction products containing TETA or DETA, water, and optionally organic compounds having a boiling point higher or lower than TETA or DETA, which are generated in the reaction of EDDN or EDMN with hydrogen in the presence of THF and a catalyst. A method, i) After the separation of hydrogen, the reaction product is fed to the distillation column DK1 where THF / water azeotropy containing further other organic compounds having a boiling point lower than that of TETA or DETA is optionally provided. The mixture is separated via the top and at the same place the bottom product containing TETA or DETA is separated, ii) the bottom product obtained from step i) above is fed to the distillation column DK2. Introduced, the THF is separated off at the top, a stream containing TETA or DETA is withdrawn from the bottom of the column, and iii) the stream from step i) withdrawn from the top of the column DK1 is condensed. The condensate or a part of the condensate is supplied with an organic solvent that is essentially immiscible with water in an amount such that phase collapse occurs, and the mixture thus obtained is separated in a phase separator, When TH And basic organic phase formed contains immiscible organic solvent and water is returned to the column DK1, wherein the water phase is discharged. |
