NONYL ACETATE Chemical Properties,Usage,Production

Description

Nonyl acetate has a floral, fruity (mushroom-gardenia) odor and a corresponding flavor on dilution. It has a bitter taste when concentrated. It is prepared by direct esterification of n-nonyl alcohol with acetic acid.

Chemical Properties

Nonyl acetate has a floral, fruity (mushroom–gardenia) odor and a corresponding flavor on dilution. It has a bitter taste when concentrated.

Chemical Properties

Colorless liquid; strong pungent odor. Soluble in four volumes of 70% alcohol, flash p 155F (68.3C), several isomers exist. Combustible.

Occurrence

Reported found in apple, citrus peel oils and juices, grapes, melon, Gruyere cheese, milk, beer and pepino fruit (Solanum muricatum).

Uses

Nonyl acetate finds some use in flavor compositions for imitation Apricot, Peach, Lemon and other Citrus types, fruit complexes, etc. Its sweet-fruity taste is accompanied by a "peel"-like freshness, and the material is quite powerful. Concentrations vary from 1 to 3 ppm in the finished product.

Definition

ChEBI: The acetate ester of nonan-1-ol.

Preparation

By direct esterification of n-nonyl alcohol with acetic acid.

Aroma threshold values

Detection: 57 to 600 ppb; aroma characteristics at 1.0%: waxy citrus, earthy mushroom, creamy milk, estry with ripe apple pulp notes.

Taste threshold values

Taste characteristics at 5 ppm: waxy, stale milk, earthy mushroom, slightly metallic with cheesy nuances.

General Description

Colorless liquid with a pungent odor of mushrooms. Less dense than water and insoluble in water. Hence floats on water.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

NONYL ACETATE 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. Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire [USCG, 1999].

Safety Profile

Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
