Process for thermal cleavage of carbamic acid esters

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 t...

Beschreibung
Zusammenfassung:	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.
