    Description

    Benzyl acetate is an organic compound with the molecular formula C9H10O2. It is the ester formed by condensation of benzyl alcohol and acetic acid.
    Benzyl acetate is found naturally in many flowers. It is the primary constituent of the essential oils from the flowers jasmine, ylang-ylang and tobira. It has pleasant sweet aroma reminiscent of jasmine. Consequently, it is used widely in perfumery and cosmetics for its aroma and in flavorings to impart apple and pear flavors.
    It is one of many compounds that is attractive to males of various species of orchid bees, who apparently gather the chemical to synthesize pheromones; it is commonly used as bait to attract and collect these bees for study.
    Benzyl acetate is also used as a solvent in plastics and resin, cellulose acetate, nitrate, oils, lacquers, polishes and inks.

    no data available

    10.2 Chemical stability

    Stable under recommended storage conditions.

    10.3 Possibility of hazardous reactions

    Combustible liquid.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. This chemical is incompatible with strong oxidizing agents. It is also incompatible with acids, bases and reducing agents.

    10.4 Conditions to avoid

    no data available

    10.5 Incompatible materials

    STABILITY: This chemical may be sensitive to light. Solutions of this chemical in water, DMSO, 95% ethanol or acetone should be stable for 24 hours under normal lab conditions.REACTIVITY: This chemical is incompatible with strong oxidizing agents. It is also incompatible with acids, bases and reducing agents.

    10.6 Hazardous decomposition products

    When heated to decomposition it emits irritating fumes.

    • Toxicity to daphnia and other aquatic invertebrates: no data available
    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    Benzyl acetate reached 92 to 96% of its theoretical BOD over a period of 4 weeks using an activated sludge seed and an initial chemical concentration of 100 mg/l(1).

    12.3 Bioaccumulative potential

    An estimated BCF of 18 was calculated for benzyl acetate(SRC), using a log Kow of 1.96(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is low(SRC).

    12.4 Mobility in soil

    The Koc of benzyl acetate is estimated as approximately 180(SRC), using a log Kow of 1.96(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that benzyl acetate is expected to have moderate mobility in soil(SRC).

    13.Disposal considerations

    13.1 Disposal methods

    Product

    The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
