Abstract

"PROCESSO PARA SEPARAR, POR RETIFICAçãO, UM LìQUIDO E QUE CONTéM áCIDO ACRìLICO". A invenção refere-se a um processo para separar, por retificação, um líquido que contém ácido acrílico, que consiste em fornecer um fluxo de material rico em ácido acrílico a uma coluna de retificação a montante de uma área de fornecimento e em realizar uma inibição de polimerização na seção do topo da coluna de retificação com a ajuda de ácido diacrílico.
