Fumaric Acid by oxidation of benzene to manufacture.
Molecular formula: C4H4O4； Molecular Weight: 116.07；
Appreance: White Crystalline
Relative density (20 ° C solid) 1.635, Melting point (sealed tube) 287
° C, Sublimation at 200 °C without decomposition, Boiling point 290
° C Low solubility in water, 25 ° C 100g of water dissolve 0.69g,
with special sour, and taste pure, strong acidity, which isabout 1.5
times of citric acid Specifications: National Standard GB/T 23877-2009.
Uses:
Fumaric acid is mainly used as food industry, sour agents,but also for
the production of unsaturated polyester resins,L-aspartic acid and L-malic
acid production, is also widely used in the production of oil additives,
adhesives,electrophoretic paint, all kinds of preservatives in pharmaceu-
tical fine chemicals.
