化學(xué)的特性
リナリルアセテートは多くの芳香族植物に自然に存在する化學(xué)物質(zhì)であり特にラベンダーの精油に高濃度で含まれていますこの成分はその甘く花のような香りで知られ香水アロマセラピー製品および個(gè)人のケア製品に広く使用されています
化學(xué)的特性
Allyl acetate is a flammable, colorless liquid with an acrid odor.
使用
Ally acetate is used in nonalcoholic beverages at 1 ppm,
ice cream and ices at 2 ppm, candy at 5 ppm, baked goods at
5 ppm, and margarine at 2 ppm.
調(diào)製方法
Allyl acetate is produced by the following methods: decarboxylation
of allylmalonic acid with heat, boiling ethyl 4-
chloro-N-valerate in quinoline, and acetoxylation of
propylene.
Allyl acetate is produced primarily for manufacturing allyl
alcohol. It is also used as a synthetic flavoring for
cheese, butter, and fruit.
安全性
リナリルアセテートは抗菌性の特性も持っていますこれは特に自然療法や伝統(tǒng)醫(yī)學(xué)で価値があるとされており空間の消臭や微生物の成長抑制に役立てられています研究では特定の細(xì)菌や真菌に対して有効な抗菌活性を示していることが報(bào)告されていますこのため自然由來の保存料として食品や化粧品に添加されることがあります
一般的な説明
A liquid. Insoluble in water and slightly less dense than water. Hence floats on water. Flash point below 75°F. Poisonous by ingestion and moderately toxic by inhalation and skin contact. Irritating to skin and eyes.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
Allyl acetate is an ester. Reacts with acids to liberate heat along with alcohols and acids. Generates heat with strong oxidizing acids. The reaction may be sufficiently exothermic to ignite the reaction products. Also generates heat with basic solutions. Generates flammable hydrogen with alkali metals and hydrides. Emits acrid smoke and irritating fumes when heated to decomposition.
危険性
Skin and eye irritant; poisonous.
健康ハザード
TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
火災(zāi)危険
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 and poison 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.
安全性プロファイル
Poison by ingestion. Moderately toxic by inhalation and skin contact. A skin and eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes. Dangerous fire hazard. See also ALLYL COMPOUNDS
職業(yè)ばく露
Allyl Acetate is used to control insects in homes and animal shelters, and to treat lice in humans. May be used to enhance taste of dairy products and fruit. Generally speaking, most allyl compounds may be metabolized to allyl alcohol (see A:0540) which is metabolized to acrolein (see A:0380).
Solubility in organics
Insoluble in water, miscible with alcohol, essential oils, perfume and flavor chemicals.
輸送方法
UN2333 Allyl acetate, Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials
合成方法
プロピレンと酢酸との反応により酢酸アリルに変換した後、加水分解する方法
純化方法
The ester is freed from peroxides by standing with crystalline ferrous ammonium sulfate, then washed with 5% NaHCO3, followed by saturated CaCl2 solution. Dry it with Na2SO4 and fractionally distil it in an all-glass apparatus. FLAMMABLE LIQUID. [Beilstein 2 H 136, 2 IV 180.]
不和合性
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. Incompatible with strong acids (liberates heat), nitrates, strong alkalis (liberates heat). Contact with alkali metals and strong reducing agents such as hydrides evolves highly flammable hydrogen gas. Attacks some plastics, coatings, and rubber. Flow or agitation of substance may generate electrostatic charges due to low conductivity; ground all equipment containing this material
廃棄物の処理
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.
