Maleic anhydride is produced by oxidation of benzene or a C4 hydrocarbon such as butane in the presence of a vanadium oxide catalyst. Maleic anhydride can be converted to maleic acid by hydrolysis and to esters by alcoholysis.
Maleic Anhydride is heterocyclic compound used in the manufacture of unsaturated polyester resins. Maleic Anhydride has a wide range of other applications; it is used in synthetic tensides, insecticides, herbicides and fungicides. Maleic anhydride has a very broad range of uses from food additives to industrial applications.
- Synthetic resin raw material (unsaturated polyesters)
- Paints and coatings
- Resin modifiers
- Vinyl chloride stabilizers
- Food additives (fumaric acid, succinic acid, malic acid)
- Agricultural chemicals
- Paper sizing agents
- Imides
- Surfactants
- Plasticizers (DOM, DBM, DEM)
- Other (GBL, 14BG, THF)
The Japan Fire Service Law does not apply to maleic anhydride. When handling, avoid contact with eyes and skin by using proper protective equipment such as goggles and gloves. If skin contact occurs, wash immediately with soap and water.

The acid anhydride of Maleic Acid synthesized from the oxidation of benzene or butane, is used to produce 1,4-butandiol (BDO) and unsaturated polyester resins (UPR). Maleic Anhydride (MA) is used to make UPR which is used for the production of plastics. Maleic anhydride is a useful chemical intermediate in in organic synthesis. It is often used to make downstream derivatives for plastics, adhesives and coatings. Its hydrolyzed form is maleic acid. Maleic anhydride is also a dispersant; it compounds with sulfurous additives and acts as a dispersant in drilling mud. Click here for more drilling fluid additives! Use: FILM FORMING
