PREPARATION OF ORGANIC DIURETHANES AND / OR POLYURETHANES AND THEIR USE FOR THE PREPARATION OF DIISOCYANATES AND / OR POLYISOCYANATES. |
| abstract |
The invention relates to a method for producing di-organic and / or polyurethane by reacting di-organic and / or polyamines (a) with urea and / or alkyl esters of carbamic acid (b) and alcohols (c) in the presence of soluble zirconia compounds, preferably zirconia alcohols, zirconia acetate and zirconia acetyl-nato, as a catalyst (d). The invention also relates to the use of these components in the production of di and / or polyisocyanates by thermal decomposition. |
