Abstract

PROCESSO PARA A PREPARAçãO DE ISOCIANATOS. A presente invenção refere-se a um método para a produção de isocianatos através da reação de aminas com fosgênio na fase gasosa em uma zona de reação, em que de modo a terminar a reação, a mistura da reação seja guiada através de uma zona, ao interior da qual um líquido é injetado. A invenção é caracterizada pelo fato de que a mistura da reação é guiada entre a zona de reação e a zona, ao interior da qual o líquido é injetado, através de uma zona com uma seção transversal de fluxo.
