1. Performance and use
Maleic acid, also known as maleic acid, is a dicarboxylic acid, which is 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
Monocrystalline colorless crystal with a bitter taste. Soluble in water, ethanol, and acetone, insoluble in benzene.
Maleic acid, also known as maleic acid, is mainly used in the production of pesticides such as marathon and daphnetin, as well as in the synthesis of unsaturated polyester resins, rosin esters, tartaric acid, fumaric acid, succinic acid and other products. It is also used in pharmaceuticals, coatings, food, printing and dyeing auxiliaries, and grease preservatives.
