Abstract
"PROCESSO PARA A PURIFICAçãO DE áCIDO ACRìLICO OU áCIDO METACRìLICO POR CRISTALIZAçãO E DESTILAçãO" A invenção refere-se a um processo para a purificação de ácido acrílico ou ácido metacrílico por cristalização e destilação, o qual consiste das seguintes etapas: (a) cristalização de uma mistura contendo o ácido acrílico ou ácido, metacrílico, resultando na produção de um produto cristalizado enriquecido com ácido acrílico ou ácido metacrílico e de uma solução-mãe; (b) destilação de pelo menos parte da solução-mãe obtida sob o estágio (a) para obter um produto de fundo de destilação que é, pelo menos parcialmente, extraído e um produto de topo; (c) cristalização de pelo menos parte do produto de topo obtido sob o estágio (b) para obter um resíduo de cristalização que é extraído e um cristalizado; e (d) recirculação do cristalizado obtido sob o estágio (c) para o processo de cristalização (a).
