Description

General description

Malonic acid (MA), also known as propanedioic acid, is a dicarboxylic acid. The crystals of MA are triclinic at room temperature. The oxidation of malonic acid by cerium (IV) in sulfuric acid solution has been studied. The reaction kinetics of the photocatalytic decomposition of MA in aqueous suspensions of titanium dioxide (TiO₂) have been described.

Application

Malonic acid may be used as a cross-linking agent between corn starch and potato starch to improve its mechanical properties.
