gamma-Valerolactone Usage And Synthesis
Chemical PropertiesColorless liquid. Surface tension 30 dynes/cm (25C), viscosity 2.18 cP (25C), pH (anhydrous): 7. pH (10% solution in distilled water): 4.2. Miscible with water and most organic solvents, resins, waxes, etc.; slightly misciblewith zein, beeswax, petrolatum; immiscible with anhydrous glycerin, glue, casein, arabic gum, and soybean protein. Combustible.
Chemical Propertiesγ-Valerolactone has a sweet, herbaceous odor.
OccurrenceReported found in boiled beef, beef fat, beer, cacao, Swiss cheese, ground and roasted coffee, roasted filberts, milk fat, dried mushroom, peach, roasted peanuts, heated pork fat, black tea and yogurt. Also reported found in peach, strawberry jam, tomato, wheaten bread, Gruyere cheese, heated butter, cooked beef, white wine, red wine, coffee and Bourbon vanilla.
Uses γ-Valerolactone is a naturally occurring chemical found in fruits and is frequently used as a food additive. It can be converted to liquid alkenes which can be used as transportation fuels. γ-Valerolactone is widely used in dye baths (coupling agent), brake fluids, cutting oils, and as solvent for adhesives, insecticides, and lacquers.
PreparationBy reduction of levulinic acid followed by cyclization.

Reactivity Profilegamma-Valerolactone is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. gamma-Valerolactone is incompatible with strong oxidizers. . gamma-Valerolactone is incompatible with strong oxidizing agents. gamma-Valerolactone is also incompatible with strong acids, strong bases and strong reducing agents. .
Safety ProfileModerately toxic by ingestion. A skin irritant. Mutation data reported. Combustible liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Purification MethodsPurify the -lactone by repeated fractional distillation [Boorman & Linstead J Chem Soc 577, 580 1933]. IR: max 1790 (CS2), 1775 (CHCl3) cm-1 [Jones et al. Can J Chem 3 7 2007 1959]. The BF3-complex distils at 110-111o/20mm [Reppe et al. Justus Liebigs Ann Chem 596 179 1955]. It is characterized by conversion to -hydroxy-n-valeramide on treatment with NH3, m 51.5-52o (by slow evaporation of a CHCl3 solution).
