Polymerization inhibitors to prevent acrylic acid polymerization
Thread Content
During the esterification reaction, a polymerization inhibitor must be added to prevent the polymerization of acrylic acid. To enhance the effect of this inhibitor, air needs to be introduced into the system. So, how should the amount of air introduced be determined? An excessive amount of air can lead to oxidation, resulting in a darker color of the product, while too little air means that the inhibitor cannot work effectively, allowing the system to undergo polymerization
