화학적 성질

Isopropyl acetate is a colourless liquid with an intense, fruity odor. On dilution, it has a sweet apple-like flavor. Miscible with most organic solvents such as alcohols, ketones and ethers. 2.9% (w/w) soluble in water at 20°C. Synthesized by direct acetylation of isopropyl alcohol in the presence of various catalysts: concentrated H2S04, diethyl sulfate, chlorosulfonic acid, and boron trifluoride.

물리적 성질

Clear, colorless liquid with an aromatic odor. Experimentally determined detection and recognition odor threshold concentrations were 2.1 mg/m³ (500 ppb_v) and 3.8 mg/m³ (910 ppb_v), respectively (Hellman and Small, 1974).

출처

Reported found in pineapple, pear, cocoa, apple, banana, black currants, grapes, melons, strawberry, cheddar cheese, beer, white wine, red wine, cocoa, honey, soybean, yellow passion fruit, beans, plum brandy and nectarines

용도

Isopropyl acetate is used as a solvent for nitrocellulose, plastics, oils, and fats, and as a flavoring agent. Isopropyl Acetate is a widely used chemical solvent in organic and industrial syntheses. Also used in the dissolution of gallstones. Environmental contaminants; Food contaminants.

주요 응용

Isopropyl acetate is a solvent in chemical industry, especially for cellulose, plastics, waxes, resins, gums, paints, oil and fats. and also as flavoring agent. It is an active component of perfumes and printing inks. It is also employed as an extractant for the preparation of antibiotics, vitamins and hormones.

정의

ChEBI: Isopropyl acetate is a branched-chain saturated fatty acid anion that is the conjugate base of isovaleric acid; reported to improve ruminal fermentation and feed digestion in cattle.

제조 방법

Isopropyl acetate is prepared from propylene and anhydrous acetic acid in the presence of a catalyst . It may also be produced by direct acetylation of isopropyl alcohol in the presence of various catalysts; concentrated H2SO4, diethyl sulfate, chlorosulfonic acid and boron trifluoride.

일반 설명

Isopropyl acetate appears as a clear colorless liquid. Flash point 40°F. Vapors are heavier than air. Contact with the material may irritate skin, eyes or mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used as a solvent.

공기와 물의 반응

Highly flammable. Less dense than water and slightly soluble in water.

반응 프로필

Isopropyl 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. Isopropyl acetate can react vigorously with nitrates, strong oxidizers, strong alkalis and strong acids. Isopropyl acetate may also attack some forms of rubber, plastics and coatings. .

건강위험

Isopropyl acetate is an irritant to the eyes,nose, and throat. Liquid irritates eyes but causes no serious injury; may cause dermatitis; no serious effects if swallowed. The acute toxicity in laboratory animals was low. Exposure to highconcentrations in air or ingestion can produce narcotic effects. A 4-hour exposure to aconcentration of 32,000 ppm in air was fatalto rats (ACGIH 1986). The oral LD50 valuein rats is in the range 6000 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.

환경귀착

Chemical/Physical. Hydrolyzes in water forming isopropyl alcohol and acetic acid (Morrison and Boyd, 1971). The estimated hydrolysis half-life at 25 °C and pH 7 is 8.4 yr (Mabey and Mill, 1978).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent concentration of 319 mg/L. The adsorbability of the carbon used was 137 mg/g carbon (Guisti et al., 1974).

Purification Methods

Wash the acetate with 50% aqueous K2CO3 (to remove acid), then with saturated aqueous CaCl2 (to remove any alcohol). Dry it with CaCl2 and fractionally distil it. [Beilstein 2 IV 141.]
