1. Product Introduction
Maleic Acid
CAS NO. 110-16-7
Molecular Formula: C4H4O4
Maleic Acid other names (Z)-butenedioic acid, cis-butenedioic acid, malenic acid, maleinic acid, toxilic acid, is a colorless crystalline compound has a faint acidulous odor and a characteristic repulsive, astringent taste. It is primarily used as a precursor to fumaric acid, and relative to its parent maleic anhydride. Maleic Acid is used in industry as an adhesion promoter for different substrates such as nylon and zinc coated metals, as a corrosion inhibitor and anti-scaling agent, and as an intermediate. Maleic acid is produced by the hydration of maleic anhydride.
