Abstract
<B>"PURIFICAçãO DE áCIDO ACRìLICO OBTIDO POR OXIDAçãO CATALìTICA DE PROPILENO"<D>. O método consiste na extração de ácido acrílico mediante lavagem de filtração em contracorrente de gases de reação, através de pelo menos um solvente pesado hidrofóbico de absorção, com uma seguinte recuperação do ácido acrílico purificado da solução obtida ao final da etapa de extração. Como solvente pesado hidrofóbico de absorção é usado pelo menos um composto aromático. tendo um ponto de ebulição sob pressão atmosférica entre 260°C e 380°C, uma temperatura de cristalização menor que 35°C e uma viscosidade menor que 10 mPa.s, em uma faixa de temperatura de 30-80°C.
