    摘要: Process for preparing a solution of pure triethylenediamine (TEDA), in which TEDA is vaporized, the gaseous TEDA is passed into a liquid solvent 1 (quench) and the TEDA is crystallized from the resulting solution and separated off (solid-liquid separation), wherein the crystalline TEDA obtained is dissolved in a solvent 2 and a stripping gas is passed through the resulting solution (stripping).
