  • Chemische Eigenschaften CLEAR COLOURLESS LIQUID
  • Chemische Eigenschaften 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
  • Chemische Eigenschaften 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.
  • Chemische Eigenschaften 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.
  • Occurrence 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.
  • Verwenden In perfumery, solvent for cellulose acetate and nitrate.
  • Definition ChEBI: The acetate ester of benzyl alcohol.
  • synthetische By interaction of benzyl chloride and sodium acetate; by acetylation of benzyl alcohol, or from benzaldehyde and acetic acid with zinc dust.
  • Aroma threshold values Detection: 2 to 270 ppb
  • Taste threshold values Taste characteristics at 40 ppm: sweet and fruity
  • Allgemeine Beschreibung Colorless liquid with an odor of pears.
  • Air & Water Reaktionen Insoluble in water.
  • Reaktivität anzeigen 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.
  • Hazard A poison by inhalation. Moderately toxic by ingestion. Combustible. Upper respiratory tract irritant. Questionable carcinogen.
  • Health Hazard 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.
  • Health Hazard 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.
  • Brandgefahr Benzyl acetate is combustible.
  • Lager Benzyl acetate should be kept stored in a cool, dry place with the container closed when not in use.
  • läuterung methode 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.]
  • Vorsichtsmaßnahmen 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
