Abstract

processo para preparar isocianatos aromáticos - a invenção refere-se a um processo para produzir isianatos aromáticos pela reação de formamidas corresppondentes com um gás contendo oxigênio sobre catalisadores de metais nobres em tempeturas de 300 <198>c a 600 <198>c e um tempo de contato de 1 ms a 1.000 ms, caracterizado pelo fato de compreender as etapas de: a. evaporar a formamida antes de entrar na zona de reação, b. inativar a mistura reacional assim obtida com um líquido de extinção contendo álcool, e c. dissociar o uretano assim formado em isocianato e álcool.
