Abstract

"PROCESSO PARA A PRODUçãO DE AMINAS AROMáTICAS". Um processo para a produção de uma amina aromática que compreende a redução de um composto aromático contendo pelo menos dois grupos nitro com hidrogênio na presença de um catalisador compreendendo um metal do Grupo VIII, sendo que a reação realiza-se de modo a manter 30% em peso ou menos de intermediários de reação e sendo que trata-se a solução produzida para recuperar a amina aromática com uma pureza acima de 99% e uma mistura compreendendo amina aromática e um intermediário de reação que é reciclado para a etapa de redução.
