PROCESS FOR HETEROGENEOUSLY CATALYZED PARTIAL GAS PHASE OXIDATION OF PROPYLENE TO ACRYLIC ACID
摘要:
A process for heterogeneously catalyzed partial gas phase oxidation of propylene to acrylic acid, in which the starting reaction gas mixture comprises cyclopropane as an impurity and the acrylic acid, after conversion from the product gas mixture into the condensed phase, is removed with the aid of a crystallative removal.
