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 In the first stage, a low-boiling fraction and a high-boiling fraction are withdrawn and discharged, and in the second stage, a medium-boiling fractions is distilled at a triethanolamin content 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

Abstract: Process for separating triethanolamine continuously by distillation from a mixture of monoethanolamine, diethanolamine and triethanolamine together with ethanolamine ethers and water obtained by reaction of ammonia with ethylene oxide in the liquid phase under superatmospheric pressure and at elevated temperature, in which the mixture is distilled in two stages. The low-boiling fraction and the high-boiling fraction are taken off and discharged in the first stage and the intermediate-boiling fraction comprising >99.4% by weight of triethanolamine and
