gamma-Valerolactone Chemical Properties,Uses,Production

Chemical Properties

Colorless 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.

Uses

Dye baths (coupling agent), brake fluids, cutting oils, and as solvent for adhesives, insecticides, and lacquers.

Reactivity Profile

gamma-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 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.

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). [Beilstein 17 H 235, 17 I 131, 17 II 288, 17 III/IV 4176, 17/9 V 24.]
