METHOD OF SEPARATING THE ACRYLIC ACID FROM BENZOIC ACID CONTAINED IN A PRODUCT GAS MIXTURE FROM A HETEROGENEOUSLY CATALYZED GAS PHASE PARTIAL OXIDATION OF C3-PRECURSOR COMPOUND OF ACRYLIC ACID

A method of separating acrylic acid-containing acrylic acid and benzoic acid in a product gas mixture from a partial oxidation, in which the acrylic acid and the benzoic acid are first converted into a liquid phase, components lighter than benzoic acid and acrylic acid are boiled away by means of th...

Summary:A method of separating acrylic acid-containing acrylic acid and benzoic acid in a product gas mixture from a partial oxidation, in which the acrylic acid and the benzoic acid are first converted into a liquid phase, components lighter than benzoic acid and acrylic acid are boiled away by means of thermal separation methods, and the acrylic acid is separated by crystallization from the remaining liquid phase.
