Maleic anhydride (chemical name: maleic acid anhydride) is a key organic chemical raw material. Maleic anhydride has an irritating odor and appears as a white crystalline powder at room temperature. When inhaled, Maleic anhydride quickly comes into contact with the respiratory mucosa. The respiratory mucosa is rich in moisture and bioactive substances, with which maleic anhydride reacts chemically: for example, it combines with moisture on the mucosa surface to form acidic substances—similar to how concentrated acid burns the skin. These acidic substances strongly irritate and corrode the respiratory mucosa, causing congestion, swelling, and in severe cases, mucosal ulceration and bleeding. Additionally, once maleic anhydride enters the body, it may spread to other organs via the bloodstream, damaging vital organs like the liver and kidneys and impairing their normal metabolism and detoxification functions.
