Abstract: A reactor for thermal cleavage of monofunctional and polyfunctional carbamic acid esters to the corresponding isocyanates and the hydroxyl components in the liquid phase, in which the geometry of the reactor, characterised by the degassing surface in proportion to the volume and the arrangement of the heating surfaces, makes possible the cleavage in a two-phase mixture which contains over 50% volumetric gas content.

Abstract: The invention relates to a multi-step method for the continuous preparation of organic polyisocyanates, preferably aliphatic or cycloaliphatic diisocyanates, by conversion of the corresponding organic polyamines with carbonic acid derivatives and alcohols into monomeric polyurethanes and thermal cleavage thereof, in which the prepared polyiisocyanates and unutilizable residues are separated off in specific reaction steps and the reutilizable by-products are fed back into preliminary steps.
