Abstract

PROCESSO PARA A PREPARAçãO DE ISOCIANATOS. A presente invenção refere-se a um processo para a preparação de isocianatos, por reação das aminas correspondentes com fosgênio, condensação da mistura de gases nesse caso resultante, esgotamento da fase líquida nesse caso obtida e reciclo do solvente assim obtido novamente de maneira líquida. Os componentes gasosos são ulteriormente recuperados, a seguir, em uma absorção.
