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: Aqueous solutions which are obtained in the carbalkoxylation of olefinically unsaturated compounds and contain heterocyclic aromatic nitrogen bases, their transformation products and lower fatty acids and/or their salts are treated by a process in which (a) the aqueous solution is heated to 150 DEG -300 DEG C. under from 10 to 300 bar and (b) heterocyclic aromatic nitrogen bases which are formed again from the transformation products are then separated off.
