Abstract: The invention relates to a process for preparing isocyanates by reaction of amines with phosgene in the presence of inert organic solvents in a reactor and subsequent work-up of the reaction mixture leaving the reactor, wherein the solvent is separated off in a two-stage or multistage, preferably two-stage, distillation process in which the solvent is separated off at a pressure of 0.1-15 bar in a first apparatus and at 1-900 mbar in a second apparatus or further apparatuses, with the heat of condensation of the solvent vapor from the first apparatus being used for partial or complete vaporization of solvent in the second apparatus.

Abstract: Dien-1-ols of the general formula I (I) where the radicals R1 to R7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl or 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxylalkenyl tert-butyl ether of the formula II (II) in the presence of an acidic catalyst at elevated tempertures and essentially at the same time splitting off the tert-butyl protective group, as is 9-hydroxydodec-10-enyl 1-tert-butyl ether which is useful as an intermediate for synthesizing 8,10-dodecadienol.

Abstract: 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.
