Beschreibung
Hexyl acetate has a pleasant fruity odor and bittersweet taste
suggestive of pear. May be synthesized from n-hexyl alcohol and
excess acetic anhydride at the boil or with an excess of acetic acid
in the presence of concentrated sulfuric acid.
Chemische Eigenschaften
Hexyl Acetate is a liquid with a
sweet-fruity, pear-like odor. It is present in a number of fruits and alcoholic beverages
and is used in fruit aroma compositions.
Occurrence
Reported found in fruital aromas (e.g., Fragaria vesca) and essential oils. Also reported found in apple, apricot,
banana, sweet cherry, citrus peel oils and juices, blueberry, black currants, guava, grapes, melon, peach, pear, raspberry, blackberry,
strawberry, peas, sauerkraut, rye bread, cheeses, roasted beef, beer, rum, cognac, whiskies, cider, sherry, grape wines, coffee, tea,
soybean, olive, passion fruit, beans, starfruit, mango, cauliflower, pear and apple brandy, quince, origanum, lovage leaf, corn oil,
mangosteen (Garcia mangostana), Bourbon vanilla, clary sage, nectarine, naranjilla fruit, Chinese quince and chamomile oil.
Verwenden
Hexyl Acetate is a flavouring agent due to its fruity odor and it is naturally present in many fruits and alcoholic beverages.
Definition
ChEBI: The acetate ester of hexan-1-ol.
Vorbereitung Methode

acetic anhydride or with an excess of acetic acid and
concentrated sulfuric acid . Its is also prepared from
primary and sec-hexyl alcohols .
It is produced by Aldrich Chemical Corp., Milwaukee, WI,
and Penta Manufacturing Co., Fairfield, NJ .
synthetische
From n-hexyl alcohol and excess acetic anhydride at the boil or with an excess of acetic acid in the presence of concentrated sulfuric acid
Allgemeine Beschreibung
A colorless liquid with a mild sweet odor. Flash point 113°F. A moderate fire risk. Inhalation may cause adverse effects. Insoluble in water and very soluble in alcohols and ethers. When heated to high temperatures emits acrid smoke and fumes. Used as a solvent and as a propellant in aerosols.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
Hexyl 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.
Hazard
Combustible.
Health Hazard
May be harmful by inhalation, ingestion, or skin absorption. May cause irritation.
Brandgefahr
Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back. Container explosion may occur under fire conditions. Forms explosive mixtures in air.
