부적합 물질로부터 차갑고 건조하고 통풍이 잘되는 곳에 보관하십시오.개요
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.화학적 성질
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 spices물리적 성질
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).출처
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.용도
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.제조 방법
By direct esterification of isobutyl alcohol with acetic acid.생산 방법
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.정의
ChEBI: The acetate ester of isobutanol.일반 설명
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 .공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
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.위험도
Flammable, dangerous fire risk.건강위험
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.화재위험
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.화학 반응
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.잠재적 노출
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 materials환경귀착
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).

UN1123 Butyl acetates, Hazard Class: 3; Labels: 3—Flammable liquid.비 호환성
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 vapors폐기물 처리
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.초산 이소부틸 준비 용품 및 원자재
