What are the Common Catalytic Processes for Acrylic Acid Production?
The two primary catalytic processes for the production of acrylic acid are:
1. Propylene Oxidation: This involves the oxidation of propylene using a catalyst, typically a mixed metal oxide. The reaction occurs in two stages: first, propylene is oxidized to acrolein, and then acrolein is further oxidized to acrylic acid. 2. Selective Oxidation of Propane: This process involves the direct oxidation of propane to acrylic acid using specialized catalysts. This method is gaining attention due to the lower cost and greater availability of propane compared to propylene.
