Abstract

PROCESSO PARA PREPARAçãO DE ANILINA. A invenção refere-se a um processo para a preparação de anilina, no qual anilina bruta é produzida por hidrogenação de nitrobenzeno em presença de um catalisador, e a anilina bruta é, a seguir, extraída com solução aquosa de hidróxido de metal alcalino, sendo que na separação da fase aquosa e da fase orgânica, a fase aquosa representa a fase inferior.
