Abstract: The invention relates to a method for distillative separation of triethanolamin from a substance mixture consisting of mono- di-, and triethanolamin, ethanolamin-ether and water obtainable by an ammonia and ethylene oxide reaction in a liquid phase at a high pressure and temperature consisting in distilling the substance mixture in two stages. In the first stage, a low-boiling fraction and a high-boiling fraction are withdrawn and discharged, and in the second stage, a medium-boiling fractions is distilled at a triethanolamin content >99.4 % by weight and a diethanolamin content
