Abstract

<B> PROCESSO PARA A HIDROGENAçãO CONTìNUA DE ADIPONITRILA". A presente invenção se refere a um processo para hidrogenação contínua de adiponitrila (DNA) em diamina de hexametileno (HMD) e opcionalmente aminocapronitrila (ACN) envolvendo a hidrogenação catalítica de adiponitrila a uma temperatura relativamente baixa (e.g. 75°C) e pressão (e.g. 500 psig) usando um catalizador de cobalto esponja (Raney<32> Co) em um meio substancialmente livre de cáustico. Em um tal processo de adição periódica de água controla-se a produção de sub-produtos e a adição periódica de hidróxido de amónio renova o catalisador. Diamina de hexametileno é um importante intermediário para a síntese de poliamidas tais como náilon 6-6 e aminocaponitrila é um potente intermediário do náilon-6.
