Abstract
MéTODO PARA PURIFICAçãO DE AMINAS AROMáTICAS. A presente invenção refere-se a um método para purificar aminas aromáticas, que foram obtidas por redução de nitrocompostos aromáticos, através da mistura da amina bruta obtida após a separação de fases com uma solução aquosa de hidróxido alcalino e em seguida através da destilação dessa mistura por meio de uma coluna de destilação, que contém pelo menos uma parte de reforço superior e uma inferior e uma parte de dessorção, sendo que o fundo da coluna de destilação é removido em parte ou totalmente e parcialmente evaporado em um evaporador principal (E1) e pelo menos em um evaporador secundário conectado em série (E2) e novamente conduzido parcialmente para a coluna.
