Perfume and Flavor Chemicals, page 1350.
Almost colorless or very pale straw-colored, slightly viscous liquid.
Practically insoluble in water, soluble in alcohol and oils, and in aqueous alkali.
Sweet, oily-fruity, Peach-like taste in concentrations lower than 20 ppm. The effect at higher concentrations is not unpleasant, but strongly fruity, supporting other fruity notes, necessarily present at high concentration of the Lactone.
The material is widely used, although in minute amounts, in perfume compositions. In order of frequency in use, it ranks very high among the materials on the perfumer’s shelf.
It blends excellently with Nonalactone in Gardenia and Tuberose, and in many versions of Lilac bases. It extends the depth of an Orangeblossom often too harsh with conventional materials, and it is a frequent component of Honeysuckle.
Its most important use today is in flavors, primarily in imitation Peach, but also in many fruity types, often as a fixative for the very volatile fruit esters.
1) By lactonization of undecylenic acid with sulfuric acid. This process will yield minor amounts of delta-isomer. 2) From Octanol-l plus Methylacrylate, with Di-tertiary-Butylperoxide. 3) From Heptyl-ethylene oxide plus Sodio-malonic ester.
