    摘要： 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

    摘要： A process for the preparation of triethylenediamine (TEDA) by reaction of ethylenediamine (EDA) in the presence of a zeolite catalyst, wherein the zeolite catalyst contains one or more metals M in oxidation states II, III or IV as oxides. The desired molar ratio of SiO2 to metal oxide of the zeolite catalyst depends on the oxidation state of the metal M as specified herein. The reaction temperature is from 250 to 500° C. TEDA is an important basic chemical and is used, among other things, in the preparation of pharmaceuticals and plastics, in particular as a catalyst in the preparation of polyurethanes.

    摘要： The present invention relates to a process for preparing TEDA solutions comprising a solvent selected from the group consisting of polyhydric alcohols and ethers of polyhydric alcohols. The process comprises passing gaseous TEDA into the solvent and subsequently treating the solutions with one or more suitable adsorbents. This gives solutions which have only low color numbers and are color-stable on storage. The solutions can be used as such in preferred applications of TEDA, preferably polyurethane production.
