    摘要: The invention relates to a process for preparing nitrogen-containing catalysts, comprising: a) preparation of an oxidic species comprising the following components: at least one metal M selected from groups Ib to VIIb and VIII of the Periodic Table of the Elements, it being possible for the same metal to be present in different oxidation states; if appropriate one or more promoters P selected from groups Ib to VIIb and VIII of the Periodic Table of the Elements, the lanthanides, and from groups IIIa to VIa of the Periodic Table of the Elements, excluding oxygen and sulfur; if appropriate one or more elements R selected from hydrogen, alkali metals and alkaline earth metals; if appropriate one or more elements Q selected from chloride and sulfate; oxygen, the molar proportion of oxygen being determined by the valency and frequency of the elements in the oxidic species other than other oxygen; b) reaction of the oxidic species with an amine component selected from ammonia, primary and secondary amines and ammonium salts, the nitrogen-containing catalyst being formed with the formation of water, and to nitrogen-containing catalysts preparable by this process. The invention further relates to a process for aminating hydrocarbons using the inventive nitrogen-containing catalyst and to the use of an oxidic species in a process for the direct amination of hydrocarbons.

      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.
