Fumaric acid is a naturally occurring organic acid with the formula C₄H₄O₄. It appears as a white crystalline powder and is the trans isomer of butenedioic acid.
🏭⚗️ Production
Fumaric acid is industrially produced by the isomerization of maleic acid or by the catalytic oxidation of benzene or fumaric acid-rich plant extracts.
🔬 Properties
• White, odorless crystalline solid with melting point around 287 °C.
• Soluble in water, alcohol, and slightly soluble in ether.
• Exhibits acidic properties due to two carboxylic acid groups.
🧪 Applications
• Food Industry: Used as an acidity regulator, food additive (E297), and flavor enhancer.
• Pharmaceuticals: Utilized in drug formulations and as a component in fumarate salts.
• Industrial: Applied in the manufacture of resins, coatings, and polyesters.
• Other Uses: Used in animal feed and as a component in dietary supplements.
