Abstract

processo contínuo de fabricação de compostos a presente invenção trata de um processo de fabricação de compostos aminados por hidrogenação de compostos nitrilas em presença de um catalisador. a presente invenção trata mais particularmente de um processo de fabricação de diaminas por hidrogenação contínua de compostos dinitrilas em presença de um catalisador à base de um metal de raney e na ausência de solvente alcoólico. este processo compreende um transvazamento de uma parte do catalisador presente no meio reacional. a parte de catalisador transvasado é submetida a um processo de regeneração para obter um catalisador com uma atividade catalítica inferior à de um catalisador virgem mais elevada. o catalisador regenerado é reciclado no meio reacional conjuntamente com catalisador virgem, de acordo com uma razão determinada. o processo da presente invenção permite em particular diminuir o consumo de catalisador por tonelada de amina produzida.
