Succinic acid is a precursor to some specialized polyesters. It is also a component of some alkyd resins. Succinic acid is used in the food and beverage industry, primarily as an acidity regulator.Global production is estimated at 16,000 to 30,000 tonnes a year, with an annual growth rate of 10%.ore recently, succinic acid has been produced through the fermentation of glucose from renewable feedstock and purification of raw bio-based succinic acid. Succinic acid can be converted into fumaric acid by oxidation. The diethyl ester is a substrate in the Stobbe condensation.
