What is Maleic Acid?
Maleic
Acid is also known as cis-butenedioic acid, toxilic acid, cis-1,2-Ethylenedicarboxylic
acid. It is commercially available as the crystalline material or
as an aqueous solution in water (40%). It may contain fumaric acid
(0.1%) and water (less than 0.5%) as impurities.
Uses : It is mainly used for making Maleate Salts of Bulk-Drugs
like Pheneramine Maleate, Chloropheneramine Maleate and others.
It is also used to prevent rancidity in oils.

Various Applications of
Maleic Acid:
Maleic acid is not very important economically, since the anhydride
is easier to use. It is employed in the manufacture of phthalic-type
alkyd and polyester resins, surface coatings, copolymers, plasticizers,
lubricant additives and agricultural chemicals; in adhesives and
sealants; as a preservative for oils and fats; organic synthesis;
dyeing and finishing wool, cotton and silk; and preparing the maleate
salts of antihistamines and similar drugs.
