Process for the preparation of pure triethylenediamine (TEDA) |
| abstract |
The invention relates to the preparation of pure triethylenediamine (TEDA) by evaporating TEDA from the mixture comprising a solvent or diluent, where the solvent or diluent has a boiling point at atmospheric pressure in the range from 175 to 250° C., passing the vapor-form TEDA into a liquid solvent, and subsequently crystallizing the TEDA out of the resultant solution. |
