3-OCTYL ACETATE Usage And Synthesis

Description

3-Octyl acetate has a characteristic, complex aroma with a rose and jasmine note and an apple-lemon undertone with a sweet, peach-like flavor.

Chemical Properties

3-Octyl acetate has a characteristic, complex aroma with a rose and jasmine note and an apple-lemon undertone with a sweet, peach-like flavor.

Occurrence

Reported found in the peppermint and pennyroyal oil (Mentha pulegium L.), spearmint oil (Mentha spicata L.), Scotch spearmint oil (Mentha cardiaca Ger.), other Mentha oils and heated beef fat.

Uses

3-Octyl acetate has found some use in perfumery as a modifier in floral-herbaceous fragrance types, since it blends equally well. with Lavender and Rose, with Opopanax and Geranium, etc. It is also used as a modifier in minty fragrance types to introduce freshness and mild, warm notes without the weedy green notes often accompanying the Mint materials. There is a considerable difference between the odor of this ester and the acetates of the isomer Octanols. Unfortunately, the title ester is one of the comparatively expensive Octanylacetates, and its use is therefore somewhat restricted. It should not be confused with the acetate of Ethyl-iso-amyl carbinol which is an inexpensive, industrial petrochemical of entirely different odor type.

Definition

ChEBI: 3-Octyl acetate is a carboxylic ester.

Taste threshold values

Taste characteristics at 10 ppm: green, oily and waxy with a weak minty and tropical nuance.

Synthesis

3-Octyl acetate is prepared by direct esteritication of 3-Octanol with Acetic acid or Acetic anhydride.
