Process for the preparation of organic diurethanes and / or polyurethanes and their use for the preparation of di- and / or polyisocyanates |
| 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. |
