Isobutyl hexanoate has a fruity odor with a cocoa-like undertone.
May be synthesized by direct esterifiication.
Isobutyl hexanoate is a colorless liquid. Almost insoluble in water, soluble in alcohol and oils. Sp.Gr. 0.86. Apple, fruity odor with cocoa-like underto
Reported found in banana, grapes, apple, apricot, beer, rum, cognac, malt whiskey, cider, sherry, grape wines,
passion fruit, apple brandy, plum wine, quince, sea buckthorn (Hippophae rhamnoides L.), spineless monkey orange and Chinese
quince peel
Isobutyl hexanoate is used extensively in flavor compositions, primarily in imitation Pineapple, but also in Apple, Grape and other fruity types. It is occasionally used for special effects in Oriental fragrances, mainly as a modifier in the fruity complex and topnote. The concentration of this ester in the finished consumer product will normally be about 8 ppm.
By direct esterification of heptanoic acid with isobutyl alcohol or by treating heptanoic acid and isobutyl alcohol in the
presence of defatted Chelidonium majus seeds at 20°C for 3 days.
ChEBI: A hexanoate ester resulting from the formal condensation of hexanoic acid (caproic acid) with isobutanol.
Aroma characteristics at 2.0%: sweet, estry, fruity pineapple, green apple, peach and tropica
Taste characteristics at 10 ppm: fruity, sweet, pineapple, green, tropical and estry.
A liquid. Flash point 198°F. Insoluble in water and less dense than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation or skin absorption. Used to make other chemicals.
ISOBUTYL CAPROATE 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.
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
