Properties
Industrial Applications
Maleic Anhydride is used in the Diels – Alder syntheses ( diene synthesis)
in co polymerisation reactions, manufacture of alkyd – type of resins, dye
intermediates, pharmaceuticals, stabilizer for polyvinylchloride, agricultural
chemicals ( maleic hydrazide, Malathion ), surfactant. It also find uses in
the production of food acids.
Handling and Storage
Maleic Anhydride must be stored in a cool, dry, well ventilated area. Areas
where there is high potential risk of fires must be avoided. Out door or
detached storage is preferable. The material should be separated from
other storage, especially from alkali metals or amines. It must be very well
protected from moisture and oxidizing materials.
Precautions
Maleic Anhydride is a powerful irritant. In contact it causes conjunctivitis ,
cornea damage, nausea, headaches, pulmonary edema and dermatitis.
Personnel must not be exposed to the concentrated vapours. Protective
clothing, chemical goggles, gloves and if necessary gas mask should be
worn when handling the material.
3 Months from date of production .
NB : Due to the effect of atmospheric moisture on Maleic Anhydride the
solidification point may be decreased and the Maleic Acid content may
exceed the limit quoted if the material is stored for a lengthy period under
humid conditions.
