Description

A reactive, white solid compound that is used in the manufacture of polyester and alkyd resins. Maleic anhydride has needle-like crystals that dissolve readily in water to form Maleic acid. It is also used in finishing processes for Paper and Permanent press textiles. Maleic acid is also used in alkyd resins to increase hardness and decrease yellowing in baking enamels (Brady 1971).

Synonyms and Related Terms

2,5-furandione; cis-butenedioic anhydride;

Risks

Corrosive. May cause burns.
Combustible. Flash point = 102 C
ThermoFisher: SDS

Physical and Chemical Properties

Dissolves in water to form maleic acid. Soluble in acetone, ethanol and dioxane. Slightly soluble in chloroform, benzene and toluene.

Composition	C4H2O3
CAS	108-31-6
Melting Point	52.8 C
Density	1.48 g/ml
Molecular Weight	mol. wt. = 98.06
Boiling Point	202 C
