Abstract

La presente invención se refiere a procedimiento para la obtención continua de monoisocianato o poliisocianato orgánicos mediante reacción de las mono- o poliaminas correspondientes a los mono- o poliisocianatos con fosgeno disuelto en disolvente orgánicos a temperaturas elevadas y subsiguiente elaboración por destilación de la mezcla de reacción resultante, el procedimiento está caracterizado porque para la obtención de la mezcla de partida, se combinan el componente amina, disuelto en caso dado en un disolvente inerte y la solución de fosgeno en una tobera, estrangulándose uno de ambos componentes en esta tobera y el otro componente se envía lateralmente en esta estrangulación a la corriente del primer componente en varias corrientes parciales, a través de un número correspondiente de orificios distribuídos en la periferia de la estrangulación.
