Propionic Acid Production Methods
1. Propylene Oxidation Process
Propylene oxidation is currently the most dominant method for producing propionic acid worldwide. Using air or oxygen as the oxidant, propylene reacts with air in the presence of a catalyst to form propionic acid. This process is characterized by high efficiency, energy savings, and environmental friendliness.
2. Acetylene Process
The acetylene method is another common production route for propionic acid. Using acetylene as the raw material, the reaction is carried out in the presence of a catalyst to form carbonyl-containing acetylenic intermediates, which are then hydrolyzed to yield propionic acid.
