There are many substances that can inhibit the polymerization of acrylic acid, and there are also many research achievements and patents in this field, such as phenolic compounds (parabisphenol, hydroquinone methyl ether, etc.), copper salts (such as copper dibutyl dithiocarbamate, etc.), nitroso compounds, phenothiazine, compounds containing - N-O groups, manganese salts (such as manganese acetate), etc. However, in industrial production, hydroquinone, copper salt, phenothiazine, hydroquinone methyl ether, etc. are commonly used as polymerization inhibitors. Among them, hydroquinone has a strong polymerization inhibition when it is oxidized to hydroquinone in the material. In a certain part of the process, a certain polymerization inhibitor can be used alone, or more than two polymerization inhibitors can be used in combination, which often shows excellent matching effect. For example, with the matching of hydroquinone and copper salt, the copper salt can not only convert hydroquinone into hydroquinone, but also form a complex with acrylic acid, which greatly reduces the activity of acrylic acid double bond, thus being inhibited from polymerization.
