What is Maleic acid CAS 110-16-7？

Maleic acid, maleic acid, is a dicarboxylic acid, an organic compound containing two carboxylic acid functional groups. Maleic acid and fumaric acid (fumaric acid) are cis-trans isomers of each other. Maleic acid is commonly used to prepare fumaric acid, maleic acid’s anhydride is maleic anhydride, compared with its acid anhydride, maleic acid has less application.

Application

Maleic acid, also known as maleic acid, is mainly used in the production of pesticides maratha, darcinone, synthetic unsaturated polyester resin, pine balsam, tartaric acid, fumaric acid, succinic acid and other products, but also used in pharmaceuticals, coatings, food and printing and dyeing AIDS and grease preservatives. Maleic acid slows the rancidity of oils and fats and can be used as a preservative and organic synthesis of oils and fats.
