Isobutyl acetate Chemical Properties,Uses,Production
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 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
Physical properties
Colorless liquid with a fruity odor. Experimentally determined detection and recognition odor threshold concentrations were 1.7 mg/m3 (360 ppbv) and 2.4 mg/m3 (510 ppbv), respectively (Hellman and Small, 1974).
Occurrence
Reported found in, apple, apricot, banana, currants, guava, grapes, melon, pear, blackcurrant, papaya, pineapple, strawberry, vinegar, wheat bread, Parmesan and Gruyere cheese, beef fat, beer, cognac, rum, cider, whiskies, sherry, grape wines, port, olive, cocoa, passion fruit, plum, starfruit, bantu beer, plum and grape brandy, mango, tamarind, apple brandy, figs, plum wine, litchi, sake, nectarine, naranjilla fruit, Cape gooseberry and Roman chamomile oil.
Uses
Isobutyl Acetate is a flavoring agent that is a clear colorless liquid with a fruity odor resembling banana when diluted. it is soluble in alcohol, propylene glycol, most fixed oils, and mineral oil, and slightly soluble in water. it is obtained by synthesis.
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.
Preparation
By direct esterification of isobutyl alcohol with acetic acid.
Definition
ChEBI: The acetate ester of isobutanol.
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
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. It produced mild to moderate irri tation on rabbits’ skin. The irritation ineyes was also mild to moderate. The LD50oral value in rabbit is within the range4800 mg/kg.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: Softens and dissolves many types of plastics; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Potential Exposure
n-Butyl acetate is an important solvent in the production of lacquers, leather and airplane dopes, and perfumes. It is used as a solvent and gasoline additive. sec-Butyl acetate is used as a widely used solvent for nitrocellulose, nail enamels and many different purposes. tert-Butyl acetate is common industrial solvent used in the making of lacquers, artificial leather, airplane dope, perfume; and as a food additive. Isobutyl acetate is used as a solvent and in perfumes and artificial flavoring materials
Environmental Fate
Chemical/Physical. Slowly hydrolyzes in water forming 2-methylpropanol and acetic acid.
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent
concentration of 180 mg/L. The adsorbability of the carbon used was 164 mg/g carbon (Guisti et
al., 1974).
Shipping
UN1123 Butyl acetates, Hazard Class: 3; Labels: 3—Flammable liquid.
Incompatibilities
All butyl acetates are incompatible with nitrates, strong oxidizers; strong alkalies; strong acids. Butyl acetates may form explosive mixture with air; reacts with water, on standing, to form acetic acid and n-butyl alcohol. Violent reaction with strong oxidizers and potassium-tert-butoxide. Dissolves rubber, many plastics, resins and some coatings. May accumulate static electrical charges, and may cause ignition of its vapors
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
