Product Description

Product Description

Basic Information

  • Product Name: Levulinic Acid
  • Chemical Formula: C5H8O3
  • Molecular Weight: 116.12 g/mol
  • Alternative Names: 4-Oxopentanoic acid, γ-Ketovaleric acid, Acetylpropionic acid
  • CAS Number: 123-76-2
  • Appearance: Colorless to light yellow viscous liquid (at room temperature); may solidify into white crystals below its melting point (mp: 33-34 °C).
  • Odor: Mild, slightly acidic smell.
  • Solubility: Highly soluble in water, ethanol, ether, and most organic solvents; miscible with polar solvents.

Physical and Chemical Properties
Physical Properties
  • Boiling Point: 245 °C (decomposes)
  • Melting Point: 33-34 °C
  • Density (20 °C): 1.133 g/mL
  • Viscosity: High viscosity due to hydrogen bonding (similar to glycerol).
  • pKa: ~4.6 (weak organic acid, dissociates in water to form levulinate ions).
Chemical Properties
  • Reactivity of Carbonyl Group: The ketone group (C=O at C4) can undergo reduction to form alcohols (e.g., 4-hydroxyvaleric acid), oxidation, or condensation reactions (e.g., with amines to form imines).
  • Acidity of Carboxyl Group: The carboxylic acid group (-COOH) enables salt formation with bases (e.g., sodium levulinate), esterification with alcohols, and amidation with amines.
  • Ring-Formation Reactions: Can cyclize under acidic conditions to form γ-valerolactone (GVL), a valuable biofuel and solvent.
  • Decarboxylation: Heats above its boiling point may cause decarboxylation, yielding acetone and carbon dioxide.

Applications
  1. Biofuels and Chemical Intermediates
    • Precursor to γ-Valerolactone (GVL): Catalytic hydrogenation of levulinic acid produces GVL, used as a bio-based solvent, fuel additive, or precursor to jet fuels and plastics.
    • Platform Chemical: Derived from renewable resources (e.g., lignocellulose), it serves as a key intermediate for synthesizing fuels, polymers, and fine chemicals.
  2. Pharmaceuticals and Biomedicine
    • Drug Synthesis: Used in synthesizing antifungal agents, antiviral drugs, and pharmaceutical intermediates (e.g., for synthesizing pyrrolidine derivatives).
    • Biomedical Materials: Ester derivatives can form biodegradable polymers for drug delivery systems or tissue engineering.
  3. Agriculture and Food Industry
    • Pesticide Intermediate: Synthesis of herbicides and insecticides (e.g., via esterification or condensation reactions).
    • Food Additive: Approved as a flavoring agent (e.g., imparting sweet, fruity notes) in some countries.
  4. Solvents and Polymers
    • Solvent for Coatings: Its esters (e.g., ethyl levulinate) act as eco-friendly solvents for paints, inks, and adhesives.
    • Polymer Synthesis: Copolymers with other acids (e.g., adipic acid) form polyesters for plastics and coatings.

Safety Considerations
  • Toxicity: Low toxicity (LD50 in rats: ~2.9 g/kg orally), but concentrated solutions are corrosive to skin and eyes.
  • Irritation: Causes skin/eye irritation; vapor may irritate respiratory tract.
  • Storage: Store in tightly sealed containers at room temperature, away from strong bases and oxidizing agents.
  • Handling: Use gloves and goggles; avoid inhalation of vapors or contact with concentrated solutions.
