Abstract: Organic diurethanes and/or polyurethanes are prepared by reacting organic diamines and/or polyamines (a) with urea and/or alkyl cabamates (b) and alcohols (c) in the presence of soluble zirconium compounds, preferably zirconium alkoxides, zirconium acetate or zirconium acetylacetonate, as catalyst (d). They can be used for preparing diisocyanates and/or polyisocyanates by thermal dissociation.

Abstract: A multistep process for the continuous preparation of organic polyisocyanates, preferably aliphatic or cycloaliphatic diisocyanates, by reacting the corresponding organic polyamines with carbonic acid derivatives and alcohols to give monomeric polyurethanes and pyrolyzing the latter involves separating the resultant polyisocyanates and worthless residues in certain reaction steps and recycling the reusable by-products into earlier steps.

Abstract: 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.
