Industrial grade fumaric acid is mainly used in unsaturated resin, organic synthesis, medicine, oil and preservative industries. This product is produced by the isomerization of maleic anhydride aqueous solution recovered from the waste gas of phthalic anhydride plant, and the product quality is in strict accordance with the national standard.
Relative molecular weight of industrial fumaric acid (fumaric acid): 116.07 physicochemical properties: This product is a white crystalline powder, melting point 286-287 ℃, easy to sublimate at 290 ℃, soluble in hot water, ethanol, slightly soluble in ether and benzene. It is heated to 230 ℃ to produce maleic anhydride due to water loss.
Application: industrial grade fumaric acid is generally used as unsaturated resin, alkyd resin, paint, etc. fumaric acid is also known as fumaric acid, and its chemical name is fumaric acid. It is an important organic basic chemical raw material and fine chemical product. It is widely used in coatings, resins, medicine, plasticizers and other fields, and can be used as food additives and feed additives.
