Description
Isobutyl acetate has a fruity (currant-pear), floral (hyacinth-rose) odor and a characteristic ether-like, slightly bitter flavor. May be prepared by direct esterification of isobutyl alcohol with acetic acid.
Chemical Properties
Isobutyl acetate, also known as 2-methylpropyl ethanoate (IUPAC name) or β-methylpropyl acetate, is a common solvent. It is produced from the esterifi cation of isobutanol with acetic acid. It is used as a solvent for lacquer and nitrocellulose. Like many esters, it has a fruity or fl oral smell at low concentrations and occurs naturally in raspberries, pears, and other plants. At higher concentrations, the odor can be unpleasant and may cause symptoms of CNS depression, such as nausea, dizziness, and headache
Chemical Properties
Isobutyl acetate is a colorless liquid with a fruit flavor. Isobutyl acetate is moisture sensitive, incompatible with ignition sources, moisture, excess heat, strong oxidizing agents, and strong bases; on decomposition, it releases carbon monoxide and carbon dioxide. It is used for nitrification fiber and paint solvents, chemical reagents, and modulation spices

Definition
ChEBI: The acetate ester of isobutanol.
Preparation
By direct esterification of isobutyl alcohol with acetic acid.
Production Methods
Isobutyl acetate may be made from methyl isobutyl ketone. It may also be made by treating isobutanol with acetic acid in the presence of catalysts. The Tischenko reaction of acetaldehyde with isobutyraldehyde yields a mixture of isobutyl acetate with ethyl acetate and isobutyl isobutyrate.
Aroma threshold values
Detection: 65 to 880 ppb
Taste threshold values
Taste characteristics at 30 ppm: sweet fruity with a banana tutti-frutti note.
General Description
A clear colorless liquid with a fruity odor. Flash point 64°F. Less dense than water (6.2 lb / gal) and insoluble in water. Vapors are heavier than air .
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
Isobutyl acetate reacts exothermically with acids to give alcohols and other acids. May react sufficiently exothermically with strong oxidizing acids to ignite the reaction products. Reactions with bases also generate heat. Combination with strong reducing agents (alkali metals and hydrides) generates flammable hydrogen.
Hazard
Flammable, dangerous fire risk.
Health Hazard
Vapors may irritate upper respiratory tract and cause nausea, vomiting, dizziness and loss of consciousness. Liquid irritates eyes and may irritate skin.
Health Hazard
Isobutyl acetate is more toxic but less of anirritant than n-butyl acetate. The toxic symp toms include headache, drowsiness, irritationof upper respiratory tract, and anesthesia.A 4-hour exposure to 8000 ppm was lethalto rats.
