Abstract: The invention relates to a multistage process for the continuous preparation of organic, distillable isocyanates, preferably diisocyanates, particularly preferably aliphatic or cycloaliphatic diisocyanates, by reaction of the corresponding organic amines with urea and alcohols to liberate ammonia and form low molecular weight monomeric urethanes and thermal dissociation of the latter, in which by-products formed are at least partly utilized.

Abstract: Aminolytic degradation of cross-linked polymer derived from 4-20C diisocyanates having urea, isocyanurate and optionally urethane and/or isocyanate structural units comprises reaction of polymer with aliphatic 8-30C mono- or diamines at 150-450 deg C whereby the reaction is carried out until the polymer has up to 20% of the initial isocyanurate, allophanate or urethane structural units. A process for the aminolytic degradation of cross-linked polymer (P), derived from 4-20C diisocyanates and optionally 1-20C aliphatic alcohols, having urea, isocyanaurate and optionally urethane and/or isocyanate structural units comprises reaction of polymer (P) with aliphatic 8-30C mono- or diamines (A) at 150-450 deg C whereby the reaction is carried out until the polymer is converted to reaction products having upto 20% of the initial isocyanurate, allophanate or urethane structural units.

Abstract: The invention provides a multistage process for continuously preparing organic, distillable polyisocyanates, preferably diisocyanates, more preferably aliphatic or cycloaliphatic diisocyanates, by reacting the corresponding organic polyamines with carbonic acid derivatives and alcohols to low molecular mass monomeric polyurethanes, and thermally cleaving said polyurethanes, in which at defined reaction stages the polyisocyanates prepared and unusable residues are separated off, and reusable by products and intermediates are recycled to upstream stages.
