29322980 | [Safety Profile]
Moderately 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. |
| Hazard Information | Back Directory | [General Description]
Clear, colorless, mobile liquid. pH (anhydrous): 7.0. pH (10% solution in distilled water): 4.2. | [Reactivity Profile]
GAMMA-VALEROLACTONE(108-29-2) 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. This chemical is incompatible with strong oxidizers. . This chemical is incompatible with strong oxidizing agents. GAMMA-VALEROLACTONE(108-29-2) is also incompatible with strong acids, strong bases and strong reducing agents. . | [Air & Water Reactions]

γ-Valerolactone has a sweet, herbaceous odor. | [Occurrence]
Reported 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. | [Definition]
ChEBI: Gamma-valerolactone is a butan-4-olide that is dihydrofuran-2(3H)-one substituted by a methyl group at position 5. It has been found in the urine samples of humans exposed to n-hexane. It has a role as a flavouring agent and a human xenobiotic metabolite. | [Preparation]
By reduction of levulinic acid followed by cyclization. | [Synthesis Reference(s)]

Odor at 1% | [Purification Methods]
Purify 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).
