Abstract

PROCESSO PARA A PREPARAçãO DE ANILINA. A presente invenção refere-se a um processo para a preparação de anilina, no qual a anilina bruta é preparada por hidrogenação de nitrobenzeno em presença de um catalisador, e a anilina bruta é purificada, a seguir, por uma destilação em um ou mais estágios, sendo que é adicionada solução de hidróxido de metal alcalino aquosa, à anilina bruta, antes da destilação, e/ou, durante a destilação da anilina bruta, é adicionada solução de hidróxido de metal alcalino aquosa.
