Abstract

"PROCESSO CONTìNUO DE HIDROGENAçãO DE COMPOSTOS". A presente invenção trata de um processo de hidrogenação de compostos que compreendem funções nitrilas ou nitrados em compostos aminas, aminonitrilas ou aminonitrados. A presente invenção propõe um processo contínuo de hidrogenação de compostos que compreendem funções nitrilas ou nitro em compostos amina ou aminonitrilas em presença de um catalisador de hidrogenação heterogênea em forma dividida e de um composto básico. A reação é realizada em um reator agitado que compreende um circuito externo de circulação do meio reacional que permite separar uma parte dos produtos hidrogenados sem extrair do catalisador, por utilização de uma filtração tangencial. O processo da presente invenção aplica-se em particular à hidrogenação da adiponitrila em uma mistura aminocapronitrila e hexametileno diamina.
