METHOD FOR THE PRODUCTION OF ACROLEIN, ACRYLIC ACID, OR A MIXTURE THEREOF BY MEANS OF HETEROGENEOUSLY CATALYZED PARTIAL GAS PHASE OXIDATION OF PROPYLENE

摘要

Disclosed is a method for producing acrolein, acrylic acid, or a mixture thereof by means of heterogeneously catalyzed partial gas phase oxidation of propylene. According to said method, the initial reaction gas mixture contains 6 to 9 percent by volume of propylene, 8 to 18 percent by volume of molecular oxygen, 6 to 30 percent by volume of propane, and 32 to 72 percent by volume of molecular nitrogen.
