Abstract
"MéTODO DE PURIFICAçãO DE áCIDO (MET)ACRìLICO". Um líquido contendo ácido (met)acrílico bruto contendo ácido acrílico é destilado em uma coluna de destilação para obter um condensado de ácido acrílico tendo uma pureza de ácido acrílico de 90% ou mais, e um gás de contendo oxigênio (ar) contendo oxigênio é fomecido ao condensado de ácido acrilico em um tanque de refluxo para receber o condensado de ácido acrílico. A presente invenção pode eficientemente produzir ácido (met)acrílico de alta pureza pela prevenção da formação de um produto polimerizado de ácido (met)acrílico no condensado obtido na produção de ácido (met)acrílico de alta pureza por destilação.
