Isobutyl acetate Usage And Synthesis
descriptionIsobutyl acetate, also known as n-propyl acetate, is the esterfication product between acetic acid and 2-butanol. It is a water-white liquid with flavor of soft fruit ester. It is slightly soluble in water, miscible with ethanol, ethyl ether as well as many other kinds of organic solvent including alcohol, ether and hydrocarbon. It can be mainly used as the diluent of nitro-lacquer and perchlorethylene paint and the solvents of nitrocellulose and lacquer as well as the substitution solvent of butyl acetate and methyl isobutyl ketone. It can also be used as a component of the flavoring agent. It can also be used as the diluent of plastic printing paste and the extraction agent in the pharmaceutical industry.
Sec-butyl acetate has excellent capability of dissolving many substances. It can be industrially applied as the solvent for manufacturing of nitrocellulose paint, acrylic paint, polyurethane paint, etc., these paints can also be used as an aircraft wing paint, artificial leather coatings and automotive coatings. Its dissolving capability is similar as n-butyl acetate and isobutyl acetate. In the coating formulation, it can be widely adopted for substitution of n-butyl acetate and isobutyl acetate. In metallic paints, people can apply butyl acetate to dissolve the cellulose acetate butyrate to obtain 15% to 20% solution.
The above information is edited by the chemicalbook of Dai Xiongfeng.
Chemical PropertiesIt is a water-white liquid with soft fruit ester flavor. It is miscible with a variety of organic solvents such as alcohols, ethers and hydrocarbons.
UsesIsobutyl Acetate can be used as organic solvent, the solvent of nitrocellulose and lacquer, extraction agent, dehydrating agents. It can also be applied to collodion, nitrocellulose, varnishes, leather, pharmaceuticals, plastics and perfume industry.
Content AnalysisIt can be determined according to the method 1 in ester assay (OT-18). The amount of the sample for taking is 1g. The equivalency factor (e) for the calculation can be taken as 58.08. Alternatively, people can apply non-polar column method via gas chromatography (GT-10-4) for the determination.
The above information is edited by the chemicalbook of Dai Xiongfeng.
ToxicityLD50: 13400 mg/kg (rat, oral).
Limited useFEMA (mg/kg): soft drinks: 11; cold drink: 16; Confectionery: 36; Bakery: 35; pudding class: 170; gum: 860; coating: 5.5.
Take appropriate amount as limit (FDA§172.515,2000).
Production methodIt can be obtained via the esterfication between iso-butanol and acetic anhydride in the presence of sulfuric acid. Mix the acetic anhydride and iso-butanol solution followed by adding drop wise of sulfuric acid. Heat for reflux of 5-6 h after a bit cooling, wash the refluxed liquid with water for 2-3 times. Use sodium carbonate for neutralizing with sodium carbonate, wash with water until neutralized, dry over calcium chloride with vacuum distillation in oil bath to derive the finished products.
DescriptionIsobutyl 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 PropertiesCLEAR LIQUID
Chemical PropertiesIsobutyl acetate is a colorless liquid with a fruit fl avor. Isobutyl acetate is moisture sensi tive, 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 nitrifi cation fi ber and paint solvents, chemical reagents, and modulation spices
Chemical PropertiesIsobutyl 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 PropertiesButyl acetates are colorless or yellowish liquids with pleasant, fruity odors. There are 4 isomers.
Physical propertiesColorless 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).
OccurrenceReported 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.
UsesIsobutyl acetate is used as a solvent and as aflavoring agent.
UsesIsobutyl 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.
UsesFlavoring, solvent.
DefinitionChEBI: The acetate ester of isobutanol.
PreparationBy direct esterification of isobutyl alcohol with acetic acid.
Production MethodsIsobutyl 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 valuesDetection: 65 to 880 ppb
Taste threshold valuesTaste characteristics at 30 ppm: sweet fruity with a banana tutti-frutti note.
General DescriptionA 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 ReactionsHighly flammable. Insoluble in water.
Reactivity ProfileIsobutyl 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.
HazardFlammable, dangerous fire risk.
Health HazardVapors may irritate upper respiratory tract and cause nausea, vomiting, dizziness and loss of consciousness. Liquid irritates eyes and may irritate skin.
Health HazardExposures to isobutyl acetate cause anesthetic effects, headaches, infl ammation of the eye characterized by redness, watering, and itching, dizziness, nausea, vomiting and a large dose may cause coma. Exposures to the skin over a longer time cause irritation and infl ammation characterized by itching, scaling, reddening and/or occasionally blistering. Exposures by ingestion and/or inhalation of isobutyl acetate cause irritation to the diges tive tract and respiratory tract. The target organs of isobutyl acetate have been reported as the CNS and skin.
Health HazardIsobutyl 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 HazardHIGHLY 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 ReactivityReactivity 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.
