Abstract
La invencion se refiere a un procedimiento para la extincion de una mezcla de reaccion gaseosa en la fosgenacion de diaminas en fase gaseosa para la fabricacion de diisocianatos. La mezcla de reaccion gaseosa comprende al menos un diisocianato, fosgeno y cloruro de hidrogeno. El liquido de extincion se pulveriza en la mezcla gaseosa que fluye de forma continua desde una zona de reaccion (1) cilindrica a la zona de extincion (5) cilindrica conectada a continuacion utilizando al menos dos toberas de pulverizacion (4) que estan dispuestas a la entrada de la zona de extincion (5) a distancias iguales a lo largo del perimetro de la zona de extincion (5).
