개요
In commercial practice amyl invariably means isoamyl, unless it is prefaced by the n- for normal. Isoamyl acetate has a powerful, fruity odor with a bittersweet taste reminiscent of pear. If impure, the odor is strong, penetrating, and almost shocking. Usually prepared by esterification of commercial isoamyl alcohol with acetic acid.화학적 성질
Isoamyl Acetate is a strongly fruity-smelling liquid and has been identified in many fruit aromas. It is the main component of banana aroma and is, therefore, also used in banana flavors.All isomers of amyl acetate are highly flammable, colorless to yellow, watery liquids.
Isoamyl acetate has a fruity, banana, sweet, fragrant, powerful odor with a bittersweet taste reminiscent of pear. If impure, the odor is strong, penetrating and almost shocking. In commercial practice, amyl invariably means isoamyl.
물리적 성질
Clear, colorless liquid with a banana or pear-like odor. Odor threshold concentration is 7 ppm (quoted, Keith and Walters, 1992). A detection odor threshold concentration of 18 μg/m3 (3.4 ppbv) was determined by Katz and Talbert (1930).출처
Reported to be found in a number of naturally occurring products, including apple, banana, cocoa bean, coffee, cognac, grape, peach, pear, pineapple and strawberry용도
Isoamyl acetate is used to impart pear flavorto mineral waters and syrups, in perfumes, inthe manufacture of artificial silk or leather, inphotographic films, in dyeing textiles, and asa solvent.정의
ChEBI: The acetate ester of isoamylol.제조 방법
By the esterification of commercial isoamyl alcohol with acetic acid생산 방법
The commerical-grade isoamyl acetate is prepared by the esterification of amyl alcohol (often fusel oil) with acetic acid and a small amount of sulfuric acid as the catalyst .일반 설명
Oily liquid; colorless; banana odor. Floats and mixes with water. Flammable, irritating vapor is produced .공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
Isoamyl acetate 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. Isoamyl acetate can react violently with oxidizing materials, nitrates, strong alkalis and strong acids.위험도
Flammable, moderate fire risk. Irritant. Explosive limits in air 1–7.5%.건강위험
Isoamyl acetate exhibits low toxicity; thetoxic effects are comparable to those of n amyl acetate. The toxic symptoms includeirritation of the eyes, nose, and throat;fatigue; increased pulse rate; and narcosis.Inhalation of its vapors at 1000 ppm for30 minutes may cause irritation, fatigue, andrespiratory distress in humans. It is more narcotic than are the lower acetic esters. TheLD50 value in rabbits is on the order of7000 mg/kg.화재위험
FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area. When heated emits acrid fumes. When exposed to flames can react vigorously with reducing materials.잠재적 노출
(n-isomer): Primary irritant (w/o allergic reaction), (sec-isomer) Human Data. Amyl acetates are used as industrial solvents and in the manufacturing and dry-cleaning industry; making artificial fruit-flavoring agents; cements, coated papers, lacquers; in medications as an inflammatory agent; pet repellents, insecticides and miticide. Many other uses.Carcinogenicity
Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.환경귀착
Chemical/Physical. Slowly hydrolyzes in water forming 3-methyl-1-butanol and acetic acid.운송 방법
UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required.Purification Methods
Dry the acetate with finely divided K2CO3 and fractionally distil it. [Beilstein 2 IV 157.]비 호환성
Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, nitrates. May soften certain plastics.폐기물 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. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.초산 이소아밀 준비 용품 및 원자재
