Abstract

''PROCESSO PARA A EXTRAçãO DE áCIDO (META) ACRìLICO DE UMA SOLUçãO AQUOSA QUE CONTéM áCIDO (META) ACRìLICO'' Uma solução aquosa a qual contém ácido (meta) acrílico é extraída colocando-a em contato com uma solução a qual contém pelo menos um agente de extração o qual pode ser convertido no ácido (meta) acrílico e forma uma diferença de miscibilidade com a solução aquosa, sendo obtidas uma fase orgânica, a qual contém o ácido (meta) acrílico e o agente de extração, em uma fase aquosa.'' PROCESS FOR THE EXTRACTION OF ACRYLIC ACID (META) FROM A WATER SOLUTION CONTAINING ACRYLIC ACID (META) '' An aqueous solution which contains (meta) acrylic acid is extracted by placing it in contact with a solution which contains hair minus an extraction agent which can be converted into (meta) acrylic acid and forms a miscibility difference with the aqueous solution, obtaining an organic phase, which contains the (meta) acrylic acid and the extraction agent, in a aqueous phase.
