    Abstract: The invention provides a multistage process for continuously preparing organic polyisocyanates, preferably diisocyanates, more preferably aliphatic or cycloaliphatic diisocyanates, by reacting the corresponding organic polyamines with carbonic acid derivatives and alcohols to give low molecular weight monomeric polyurethanes and cleaving the latter. The invention further provides a corresponding preparation process in which the polyisocyanates prepared and unutilizable residues are removed at particular reaction stages, and reusable by-products and intermediates are recycled into preceding stages.

    Abstract: The invention relates to a multi-stage method for the continuous production of organic, distillable polyisocyanates, preferably diisocyanates, especially preferably aliphatic or cycloaliphatic diisocyanates, by reacting the corresponding organic polyamines with carbonic acid derivatives and alcohol in low-molecular monomer polyurethanes and to the thermal splitting of the latter. During said method, the polyisocyanates produced and unusable residues are separated at specific reaction stages and reusable secondary and intermediate products are recirculated to the initial stages.
