This product is mainly used for the production and storage of the inhibitor of vinyl monomers,such as acrylonitrile, acrylic acid and ester, methyl acrylic acid and ester. Its best advantage lies on that the monomer can participate in the polymerization without removing the MEHQ in it. It can be also used for the synthesis of anti-aging agent, plasticizer and food antioxidant.
