HEPTYL ACETATE Chemical Properties,Usage,Production

Description

Heptyl acetate has a pleasant odor suggestive of pear (rose) and a sweet apricot-like taste. May be synthesized from n-heptyl alcohol and acetyl chloride in ether solution in the presence of magnesium dust.

Chemical Properties

Heptyl acetate has a pleasant odor suggestive of pear (rose) and a sweet, apricot-like taste.

Occurrence

Heptyl alcohol has been reported found in the essential oil of Litsea zeylanica; the corresponding ester has not yet been identifed among the constituents of essential oils Also reported found in fresh apple, apricot, banana, citrus peel oils, melon, pear, plum, Japanese plum, quince, ginger, blue cheese, beef fat, beer, rum, malt whiskey and sparkling wine

Uses

Artificial fruit essences.

Definition

Liquid with fruity odor.

Preparation

From n-heptyl alcohol and acetyl chloride in ether solution in the presence of magnesium dust.

Aroma threshold values

Detection: 320 ppb.

Taste threshold values

Taste characteristics at 7 5 ppm: green, fatty, spicy, citrus, soapy and aldehydic with a foral nuance.

General Description

Colorless liquid.

Reactivity Profile

HEPTYL 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.

Health Hazard

May be harmful by inhalation, ingestion or skin absorption. Irritating to eyes, skin, and mucous membrane.

Fire Hazard

Special Hazards of Combustion Products: When heated to decomposition, HEPTYL ACETATE emits acrid smoke and fumes.

Synthesis

Heptyl acetate is synthesized by direct esterification of n-Heptanol with Acetic acid under azeotropic conditions, or with Acetic anhydride.

Solubility in organics

Miscible with alcohol and oils. Soluble in propylene glycol.
