levulinic acid (CAS No. 123-76-2)
levulinic acid (CAS No. 123-76-2) is a white flake crystal with hygroscopic properties.
Levulinic acid can be used as a carboxylic acid reaction, but also as a ketone reaction, can occur esterification, fontanation, hydrogenation, oxidative dehydrogenation, condensation and other reactions. And reaction generation trace; Reacts with a base to form a salt; React with alcohol to produce ester, etc. Oxidation, reduction and halogenation can also occur. Aqueous solution is more acidic than acetic acid. Atmospheric distillation almost does not decompose, and long-term heating will lose water and generate unsaturated gamma-lactone.
Levulinic acid is soluble in water, alcohol, ether, fat, ketone and aromatic hydrocarbons, but insoluble in aliphatic hydrocarbons, gasoline, kerosene, turpentine and carbon tetrachloride.
Levulinic acid is used as a raw material for pharmaceuticals, fragrances, resins, pesticides, organic synthesis intermediates, coatings, and as a solvent. In the pharmaceutical industry, its calcium salts can be made into intravenous injections and anti-inflammatory drugs. Its lower esters can be used as food flavors or tobacco flavors. The bisphenol acid obtained from this product can produce water-soluble resin, which can be used to produce filter paper in paper industry. It can also be used to produce pesticides (such as plant hormones, etc.), plastic modifiers, dyes, surfactants, polymer additives, lubricating oil additives, coating additives, printing ink, rubber additives, cosmetic additives (including shampoo, toiletries), etc.
