摘要： The invention concerns a method of producing organic di- and/or polyurethanes by reacting organic di- and/or polyamines (a) with urea and/or carbamic acid alkyl esters (b) and alcohols (c) in the presence of soluble zirconium compounds, preferably zirconium alcoholates, zirconium acetate or zirconium actylacetonate, as a catalyst (d). The invention also concerns the use of such compounds in the production of di- and/or polyisocyanates by thermal decomposition.

摘要： The invention relates to a method for producing mixtures consisting of diphenylmethane diisocyanates and polyphenylene-polymethylene-polyisocyanates containing a reduced amount of chlorinated secondary products and with a reduced iodine colour index. According to said method, a two-stage reaction of the corresponding mixtures of diphenylmethane-diamines and polyphenylene-polymethylene polyamines with phosgene is carried out in the presence of at least one inert organic solvent at a high temperature. When the phosgenation is complete, the excess phosgene and solvent are separated off and the product of the reaction is treated with heat. The method is characterised in that the mass ratios of phosgene to hydrogen chloride in the detention apparatus in the second stage of phosgenation are simultaneously 10-30:1 in the liquid phase and 1-10:1 in the gas phase.

摘要： The invention relates to a method for producing amines by hydrogenating nitro compounds and is characterized in that the hydrogenation is carried out in a vertical reactor whose diameter is larger than its length. The reactor comprises a jet nozzle which is arranged in the upper area of the reactor and which is directed downwards. The educts and the reaction mixture are delivered via said jet nozzle. The reactor also comprises an outlet situated in any position of the reactor via which the reaction mixture in an outer circuit is delivered once again to the jet nozzle by means of a conveying organ, and the reactor has a flow reverse situated in the lower area of the reactor.

摘要： The invention relates to a method for the production of methylenedi(phenylamine) by reacting aniline with formaldehyde in the presence of acid catalysts. The method is characterized in that aniline and optionally an acid catalyst are treated in a semi-continuos method; formaldehyde and optionally an acid catalyst are fed through a mixing organ in a circuit in which aniline, optionally an acid catalyst and optionally an already added formaldehyde are circulated and tempering the reaction mixture at a temperature of over 75 °C after feeding at least 50 % of the total amount of formaldehyde. The invention also relates to a method for the production of polyisocyanates by phosgenating the amines thus obtained and the polyisocyanates obtained according to this method.

摘要： The invention relates to a method for producing isocyanates by reacting amines with phosgene inside a reactor followed by separating the isocyanate out from the reaction mixture exiting the reactor and purifying this isocyanate. The invention is characterized in that the isocyanate is separated out and purified in a column with a top pressure of 1 to 950 mbar, preferably 5 to 50 mbar, particularly preferred 10 to 20 mbar, with a bottom temperature of 90 to 250 °C, preferably 120 to 170 °C, particularly preferred 130 to 150 °C, and that the pure isocyanate flow is withdrawn in liquid or gaseous form, preferably in a side-stream of the column.
