化学的特性

Butyl acetates are colorless or yellowish liquids with pleasant, fruity odors. There are 4 isomers.

化学的特性

Butyl Acetate is a liquid with a strong fruity odor. It occurs in many fruits and is a constituent of apple aromas.

化学的特性

Butyl acetate has a strong, fruity odor; burning and then sweet taste reminiscent of pineapple.

物理的性質

Clear, colorless liquid with a strong fruity odor resembling bananas. Sweetish taste as low concentrations (<30 μg/L). Experimentally determined detection and recognition odor threshold concentrations were 30 μg/m3 (6.3 ppbv) and 18 μg/m3 (38 ppbv), respectively (Hellman and Small, 1974). Cometto-Mu?iz et al. (2000) reported nasal pungency threshold concentrations ranged from approximately 550 to 3,500 ppm.

天然物の起源

Reported present in rum ether, pears, pear brandy, cider, mango, mountain papaya (C. pubescens), soybean, roasted peanuts and honey and other natural products.

使用

n-Butyl acetate is used in the manufactureof lacquers, plastics, photographic films, andartificial leathers.

使用

Butyl Acetate is a flavoring agent which is a clear, colorless liquid possessing a fruity and strong odor. it is sparingly soluble in water and miscible in alcohol, ether, and propylene glycol. it is also termed n-butyl acetate.

使用

manufacture of lacquer, artificial leather, photographic films, plastics, safety glass.

定義

ChEBI: The acetate ester of butanol.

製造方法

By esterification of n-butyl alcohol with acetic acid.

Aroma threshold values

Detection: 10 to 500 ppb

一般的な説明

A clear colorless liquid with a fruity odor. Flash point 72 - 88°F. Density 7.4 lb / gal (less than water). Hence floats on water. Vapors heavier than air.

空気と水の反応

Highly flammable. Very slightly soluble in water.

反応プロフィール

Butyl 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. Attacks many plastics. [Handling Chemicals Safely 1980. p. 233].

危険性

Skin irritant, toxic. Flammable, moderate fire risk. Eye and upper respiratory tract irritant.

健康ハザード

The narcotic effects of n-butyl acetate isgreater than the lower alkyl esters of aceticacid. Also, the toxicities and irritant actionsare somewhat greater than n-propyl, iso propyl, and ethyl acetates. Exposure to itsvapors at about 2000 ppm caused mild irri tation of the eyes and salivation in test ani mals. A 4-hour exposure to 14,000 ppm wasfatal to guinea pigs. In humans, inhalation of300–400 ppm of n-butyl acetate may pro duce moderate irritation of the eyes andthroat, and headache.

健康ハザード

Exposures to n-butyl acetate cause harmful effects that include, but are not limited to, coughing and shortness of breath. High concentrations have a narcotic effect, with symp toms such as sore throat, abdominal pain, nausea, vomiting, and diarrhea. High concen trations of n-butyl acetate cause severe poisoning. Prolonged periods of exposure cause adverse effects to the lungs, the nervous system, and the mucous membranes. Repeated skin contact causes skin dryness or cracking, and dermatitis

健康ハザード

SKIN: prolonged or frequently repeated exposures may lead to drying. INHALATION: headaches, dizziness, nausea, irritation of respiratory passages and eyes.

火災危険

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 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.

化学反応性

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

安全性プロファイル

Moderately toxic by intraperitoneal route. Mdly toxic by inhalation and ingestion. An experimental teratogen. A skin and severe eye irritant. Human systemic effects by inhalation: conjunctiva irritation, unspecified nasal and respiratory system effects. A mild allergen. High concentrations are irritating to eyes and respiratory tract and cause narcosis. Evidence of chronic systemic toxicity is inconclusive. Flammable liquid. Moderately explosive when exposed to flame. Ignites on contact with potassium tert-butoxide. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid and irritating fumes. See also ESTERS.

職業ばく露

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 materials

Source

Identified as a volatile constituent released by fresh coffee beans (Coffea canephora variety Robusta) at different stages of ripeness (Mathieu et al., 1998). Also identified among 139 volatile compounds identified in cantaloupe (Cucumis melo var. reticulates cv. Sol Real) using an automated rapid headspace solid phase microextraction method (Beaulieu and Grimm, 2001).

環境運命予測

Biological. Heukelekian and Rand (1955) reported a 5-d BOD value of 0.52 g/g which is 23.5% of the ThOD value of 2.21 g/g.
Photolytic. Butyl acetate reacts with OH radicals in the atmosphere at a rate constant of 4.15 x 10-12 cm3/molecule?sec at 296 K (Wallington et al., 1988b).
Chemical/Physical. Hydrolyzes in water forming 1-butanol and acetic acid. Estimated hydrolysis half-lives at 20 °C: 11.4 d at pH 9.0, 114 d at pH 8.0, and 3.1 yr at pH 7.0 (Mabey and Mill, 1978).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent concentration of 154 mg/L. The adsorbability of the carbon was 169 mg/g carbon (Guisti et al., 1974).

貯蔵

n-Butyl acetate should be kept stored in a segregated and approved area. Workers should keep the container in a cool, well-ventilated area, closed tightly, and sealed until ready for use. Workers should avoid all possible sources of ignition/spark at the workplace

輸送方法

UN1123 Butyl acetates, Hazard Class: 3; Labels: 3—Flammable liquid.

純化方法

Distil, reflux with successive small portions of KMnO4 until the colour persists, dry with anhydrous CaSO4, filter and redistil. [Beilstein 2 IV 143.]

不和合性

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 vapors

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.

予防処置

On exposure to n-butyl acetate, immediately wash with plenty of water, also under the eyelids, for at least 15 min. Remove contact lenses. n-Butyl acetate is flammable in the pres ence of open flames, sparks, oxidizing materials, acids, and alkalis. It poses explosion risk in the presence of mechanical impact. For health safety, management authorities should provide exhaust ventilation facilities at the workplace to keep the airborne concentrations of vapors of n-butyl acetate below TLV
