Maleic Anhydride
Synonyms ：MA；2,5-FURANDIONE；2,5-Furandione；furan-2,5-dione；MaleicAnhydride；Maleic anhydride；ANHYDRIDE MALEIC；TOXILIC ANHYDRIDE；Sodium n-amylxanthate；cis-Butenedioic anhydride
CAS NO.:108-31-6
EINECS ：203-571-6
Molecular Formula : C4H2O3
Molecule Weight : 98.06
Melting Point : 51-56 °C
Boling Point : 200 °C
Properties : Character orthorhombic crystal system colorless needle-like or plate-like crystals. Soluble in water to produce maleic acid. Dissolve in ethanol and produce esters.Sublimated by heat. In case of high heat, open flame or contact with oxidant, there is a risk of combustion. Corrosive. Slowly
hydrolyze in cold water to produce maleic acid. Contact with strong oxidants can cause combustion and explosion. If the temperature exceeds 66 ° C., the polymerization reaction may occur in contact with amines or alkali metals.
