Mo3121 LeA 25,711 PROCESS FOR THE CONTINUOUS PREPARATION OF MONOISOCYANATES OR POLYISOCYANATES ABSTRACT OF THE DISCLOSURE The present invention relates to a process for the continuous preparation of organic mono or polyiso- cyanates by the reaction of the mono- or polyamines corresponding to the mono- or polyisocyanates with phosgene dissolved in an organic solvent. The phosgene solution and the amine component, optionally also in the form of a solution, are brought together inside a nozzle (1) by subjecting the stream of one component to a constriction (3) and supplying the other component into this constriction (3) from the side as partial streams through several apertures (5).
