CAS 108-31-6

Maleic anhydride

Description:

Maleic anhydride, with the CAS number 108-31-6, is a colorless to white crystalline solid that is highly reactive and has a pungent odor. It is an unsaturated cyclic anhydride derived from maleic acid and is primarily used in the production of various chemical intermediates, including resins, plastics, and agricultural chemicals. Maleic anhydride is soluble in organic solvents such as acetone and ethanol but has limited solubility in water. It is known for its ability to undergo various chemical reactions, including polymerization, addition reactions, and esterification. Due to its reactivity, it can form adducts with alcohols and amines. Maleic anhydride is also a key component in the synthesis of copolymers and is utilized in the manufacture of coatings, adhesives, and surfactants. However, it is important to handle this substance with care, as it can be irritating to the skin, eyes, and respiratory system, and appropriate safety measures should be taken during its use and storage.

Maleic anhydride

CAS: 108-31-6

Maleic anhydride is the monomer of an aliphatic unsaturated anhydride that reacts with a hydroxyl group to form an ester. It has been used as a chemical intermediate, as well as in the production of polymers. Maleic anhydride is also used in the manufacture of some inhalers and nebulizers to deliver drugs to the lungs. Maleic anhydride has inhibitory properties against chronic bronchitis, which may be due to its ability to inhibit the formation of 2-aminoterephthalic acid from terephthalic acid and ammonia. Maleic anhydride can be used for the oxidation of various alcohols and amines, but it does not oxidize carboxylic acids or aromatic compounds. Maleic anhydride is soluble in water vapor and reacts with oxygen in air at elevated temperatures, forming maleates and water. FTIR spectroscopy can be used to identify this compound by examining its absorption bands
