Uses and synthesis of Maleic acid powder

Maleic acid powder, maleic acid, is a dicarboxylic acid, i.e., an organic compound containing two carboxylic acid functional groups.Maleic acid CAS 110-16-7 and transbutylene dicarboxylic acid (fenugreek) are cis-trans isomers of each other.

Maleic acid is commonly used in the preparation of transbutylene dicarboxylic acid. Maleic acid Raw Materials' anhydride is maleic anhydride, which has fewer applications than its anhydride.

Applications / Functions of Maleic acid powder

Maleic acid powder, also known as maleic acid, is mainly used in the production of pesticide marathon, dapsone, synthetic unsaturated polyester resins, rosin, tartaric acid, transbutylene dioic acid, succinic acid and other products, Maleic Acid CAS 110-16-7 is also used in pharmaceuticals, coatings, food and dyeing auxiliaries, and stains preservative and so on.

Alkalinity method analysis standard, slow down the rancidity of oil and fat can be used as oil and grease preservatives, organic synthesis.

Physicochemical Property of Maleic acid powder

Colourless crystal of monoclinic crystal system, with astringent taste. Soluble in water, ethanol and acetone, insoluble in benzene.

Production methodprocess of Maleic acid powder

• 1.Benzene oxidation method after preheating pure benzene, under the action of vanadium series catalyst, air oxidation to generate maleic anhydride, the reaction temperature is 360 ℃, and then by the water absorption, concentration, crystallisation and drying of Maleic acid Raw Materials.
• 2. Butene (alkane) oxidation method Butene (alkane) under the action of vanadium catalyst, air oxidation to generate maleic anhydride, the reaction temperature of 350-450 ℃, and then by water absorption to generate maleic acid, and then by concentration, drying Maleic acid powder.
• 3. Other production methods (1) naphthalene or o-xylene oxidation to generate phthalic anhydride by-production of maleic acid; (2) furfural oxidation method, this method is not used because of efficiency issues.
