    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: In a process for the purification of triethylenediamine (TEDA) in which TEDA is vaporized and the gaseous TEDA is passed into a liquid solvent and is subsequently crystallized from this, the mother liquor obtained after the TEDA has been crystallized is extracted with an extractant which is immiscible or only slightly miscible with the solvent of the mother liquor and in which TEDA is readily soluble, and the TEDA-depleted mother liquor obtained after extraction and/or the TEDA-enriched extractant which has been used for the extraction are/is returned to the process.

    摘要: The present invention describes a process for the preparation of triethylenediamine by reacting piperazine over a zeolite catalyst which, in addition to SiO2, contains an oxide of at least one further divalent, trivalent or tetravalent metal M, wherein the zeolite has a molar Si/M ratio of >100. In particular, a zeolite of the ZSM-5 type is used. The use of the zeolites permits suppression of the undesired formation of the byproduct 2-ethylpiperazine and hence considerable simplification of the working-up, in combination with high piperazine conversions and a small excess of water.
