PROCESSO PARA A PREPARACAO CONTINUA DE MONOISOCIANATOS OU POLIISOCIANATOS |
摘要 |
In order to improve the economics of the continuous preparation of organic mono- or polyisocyanates by reaction of the mono- or polyamines, corresponding to the mono- or polyisocyanates, with phosgene dissolved in an organic solvent, the phosgene solution and the optionally dissolved amine component are combined in a nozzle (1) by subjecting the stream of one component to a constriction (3) and introducing the other component into this constriction (3) laterally as individual streams through a plularity of orifices (5).
