Abstract
"PROCESSO PARA A HIDROGENAçãO CATALìTICA HETEROGêNEA DE UMA AMINA AROMáTICA EM UM VASO DE REATOR". Essa invenção refere-se a um aperfeiçoado processo para a preparação de ciclohexilaminas onde uma amina aromática é contatada com hidrogênio em presença de um catalisador de hidrogenação. O aperfeiçoamento reside na utilização de um catalisador de hidrogenação composto de metal ródio, utilizando um solvente éter de dialquila, e efetuando retardo da adição da diamina aromática ao meio reacional.
