Description

γ-Heptalactone has a sweet, coconut-like, caramel and a malty, caramel, sweet odor, and herbaceous taste. Clear colorless to pale yellow liquidy-Heptalactone has a sweet, nut-like, caramel odor and a malty, caramel, sweet, herbaceous taste. This substance may be obtained in low yields by hydrogenation of ethyl P-furylacrylate;1 by lactoniation of heptenoic acid; also by condensation of methylacrylate butyl alcohol using a catalyst.

colourless, slightly oily liquid with a coconut, sweet, malty, caramel odour
