Benzyl acetate Usage And Synthesis
CLEAR COLOURLESS LIQUID
Benzyl acetate is a colorless liquid with a fruity odor. On burning and decomposition, it produces irritating fumes. Benzyl acetate reacts with strong oxidants causing fi re and explosion hazard
is the main component of jasmine absolute and gardenia oils. It occurs as a minor component in a large number of other essential oils and extracts. It is a colorless liquid with a strong, fruity, jasmine odor. Benzyl acetate is prepared by esterification of benzyl alcohol with acetic anhydride (e.g., with sodium acetate as a catalyst) or by reaction of benzyl chloride with sodium acetate. In terms of volume, benzyl acetate is one of the most important fragrance and flavor chemicals.
Benzyl acetate has a characteristic flowery (jasmine) odor and a bitter, pungent taste. It is present as a main constituent in several oils and flower absolutes. Although benzyl acetate is present in some essential oils at levels up to 65%, most of the commercial product is of synthetic origin.
Present as a main constituent in several oils and flower absolutes: ylang-ylang, cananga, neroli, jasmine, hyacinth, gardenia, tuberose. It has been isolated from the essential oil of the flowers of Loiseleuria procumbens Desv. (azelea). Also reported found in apricot, cooked asparagus, mozzarella cheese, grilled beef, cooked pork, malt whiskey, fresh mango, malt, wort and clams.
Benzyl acetate is used as an artificial jasmine and other perfumes, soap perfume, flavoring agent, solvent for cellulose acetate and nitrate, natural and synthetic resins, oils, lacquers, polishes, printing inks, and varnish removers.
In perfumery, solvent for cellulose acetate and nitrate.

Air & Water Reactions
Insoluble in water.
Benzyl 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. Benzyl acetate is incompatible with strong oxidizing agents. Benzyl acetate is also incompatible with acids, bases and reducing agents.
A poison by inhalation. Moderately toxic by ingestion. Combustible. Upper respiratory tract irritant. Questionable carcinogen.
Harmful if inhaled. May be harmful if swallowed or absorbed through the skin. Vapor or mist is irritating to the eyes, mucous membrane and upper respiratory tract.
Exposures to benzyl acetate cause adverse health effects. The symptoms of toxicity and poisoning include irritation to the skin, eyes, burning sensation, confusion, dizziness, drowsiness, labored breathing, sore throat, nausea, vomiting, and diarrhea. Benzyl acetate also causes adverse health effects to the respiratory tract and the CNS system with neurological effects.
Benzyl acetate is combustible.
A poison by inhalation.Moderately toxic by ingestion and subcutaneous routes.Human systemic effects by inhalation: an antipsychotic,unspecified respiratory and urinary system effects.Questionable carcinogen with experimental tumorigenicdata. Combusti

The esters of benzyl alcohol, such as the acetate, benzoate, cinnamate and hydrocinnamate, are rapidly hydrolysed in vivo to benzyl alcohol which is then oxidized to benzoic acid and excreted as hippuric acid
Benzyl acetate should be kept stored in a cool, dry place with the container closed when not in use.
Purify the acetate by fractional distillation, preferably in a good vacuum. Values of n25 of 1.5232-1.5242 are too high and should be nearer to 1.4994. [Merker & Scott J Org Chem 26 5180 1961, Beilstein 6 IV 2262.]
Exposures to benzyl acetate far above the OEL may result in unconsciousness. After handling and using benzyl acetate, workers should wash thoroughly and remove contaminated clothing, washing it before reuse. Workers should avoid any kind of contact of benzyl acetate with the eyes, skin, ingestion, and inhalation. Workers should wear safety glasses and chemical goggles to avoid splashing of the chemical substance during work, and wear appropriate protective gloves and clothing to prevent skin exposure
