Abstract
processo para separar ácido acrílico, presente como um produto principal, e glioxal, presente como um subproduto em uma mistura gasosa a invenção refere-se a um método para a separação de ácido acrílico, contido como o constituinte principal e glioxal, contido como um subproduto, a partir de uma mistura de produto gasosa da oxidação em fase gasosa parcial de um composto precursor c3 de ácido acrílico. de acordo com o referido método, é criada uma fase líquida p, da qual 70% do peso total consiste de ácido acrílico e que contém, pelo menos, 200 ppm molar de glioxal em relação à quantidade molar contida de ácido acrílico. o glioxal é separado a partir do ácido acrílico através de cristalização a partir da fase líquida p.
