Chemical Properties
Cyclohexyl acetate is a clear colorless to pale yellow, oily, and flammable liquid that has an odor reminiscent of amyl acetate. It is very slightly miscible with water, but completely miscible with common organic solvents. Its solvency properties are comparable to those of amyl acetate. It is used for the production of pigment pastes on account of its good solvency for basic dyes. It is also employed as a fragrance component in the perfume industry.
Occurrence
Reported found in sauerkraut.
Uses
Cyclohexyl Acetate is a synthetic flavoring agent that is a stable,
colorless liquid of fruity odor. it is stored in glass, tin, or resin-lined
containers. it is used for flavors such as apple, banana, blackberry,
and raspberry with applications in beverages, ice cream, candy, and
baked goods at 15–110 ppm.
Preparation
By heating the corresponding alcohol with acetic anhydride or acetic acid in the presence of traces of sulfuric acid.
Definition
ChEBI: Cyclohexyl acetate is a carboxylic ester.
Production Methods
Cyclohexyl acetate is manufactured by direct esterification
of cyclohexanol and alternatively by heating alcohol with
acetic anhydride in the presence of sulfuric acid.
Taste threshold values
Taste characteristics at 30 ppm: solventy and slightly cooling with sweet banana and apple notes.
General Description
Cyclohexyl acetate appears as a colorless liquid. Flash point 136°F. Slightly less dense than water and insoluble in water. Vapors are much heavier than air and may be narcotic in high concentrations. May emit acrid smoke and irritating fumes when heated to high temperatures. Used as a solvent and in making rubber.
Air & Water Reactions
Flammable. Insoluble in water.
Reactivity Profile
CYCLOHEXANOL 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. Causes eye and skin irritation.
Fire Hazard
Special Hazards of Combustion Products: Emits toxic fumes under fire conditions. Vapor may travel considerable distance to a source of ignition and flash back.
Safety Profile
Moderately toxic by
subcutaneous route. Mildly toxic by
ingestion and skin contact. Human systemic
effects by inhalation: conjunctiva irritation
and unspecified respiratory system changes.
A systemic irritant to humans. A skin and
eye irritant. Flammable liquid when exposed
to heat or flame. When heated to
decomposition it emits acrid smoke and
irritating fumes.
