化学的特性

liquid with a butter-like odour

化学的特性

2,3-Butanedione is a constituent of many fruit and food aromas and well-known as a constituent of butter. Many methods are known for itsmanufacture, for example, dehydrogenation of 2,3-butanediol with a copper chromite catalyst. Biotechnological production on an industrial scale is referred. It is used mainly in aromas for butter and roasted notes. Large quantities are used for flavoring margarine; small amounts are used in perfumes.

化学的特性

Diacetyl has a very strong buttery odor in very dilute solution.

天然物の起源

Reported in the oils of: Finnish pine, angelica and lavender; in the flowers of Polyalthia canangioides Boerl. var. angustifolia and Fagroea racemosa Jack. The following plants are also reported to contain diacetyl: Monodora grandiflora Benth., Magnolia tripetale L., Ximenia aegyptiaca L., Petasites fragrans Presl., various narcissi and tulips. It has been identified in certain types of wine, the natural aromas of raspberry and strawberry, and the oils of lavender, lavandin, Réunion geranium, Java citronella, and Cistus ladaniferus L. It is also reported to be found in ligonberry, guava, raspberry, strawberry, cabbage, peas, tomato, vinegar, various cheeses, yogurt, milk, butter, chicken, beef, mutton, pork, cognac, beer, wines, whiskies, tea and coffee.

使用

2,3-Butanedione is a flavoring agent that is a clear yellow to yellowish green liquid with a strong pungent odor. It is also known as 2,3-butanedione and is chemically synthesized from methyl ethyl ketone. It is miscible in water, glycerin, alcohol, and ether, and in very dilute water solution it has a typical buttery odor and flavor.

使用

Inactivates aminopeptidase-N.1 Cyclocondensation with amines has been used to form triazine2 and pteridine ring systems.3 Also used as a precursor to α-diones.4

使用

Carrier of aroma of butter, vinegar, coffee, and other foods.

定義

ChEBI: An alpha-diketone that is butane substituted by oxo groups at positions 2 and 3. It is a metabolite produced during the malolactic fermentation.

製造方法

From methyl ethyl ketone by converting to the isonitroso compound and then decomposing to diacetyl by hydrolysis with HCl; by fermentation of glucose via methyl acetyl carbinol.

Aroma threshold values

Detection: 0.3 to 15 ppb: recognition: 5 ppb

Taste threshold values

Taste characteristics at 50 ppm: sweet, buttery, creamy and milky.

一般的な説明

A clear colorless liquid with a strong chlorine-like odor. Flash point 80°F. Less dense than water. Vapors heavier than air.

空気と水の反応

Highly flammable. Soluble in water.

反応プロフィール

2,3-Butanedione is a flammable liquid, b.p. 88° C, moderately toxic. When heated to decomposition 2,3-Butanedione emits acrid smoke and fumes [Sax, 9th ed., 1996, p. 544].

健康ハザード

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.

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.

安全性プロファイル

A poison by ingestion and intraperitoneal routes. A skin irritant. Human inhalation hazard in popcorn manufacture. Human mutation data reported. Flammable liquid. Dangerous fire hazard when exposed to heat or flame. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also KETONES.

毒性学

Diacetyl is an intensely yellowish or greenish-yellow mobile liquid. It has a very powerful and diffusive, pungent, buttery odor and typically used in flavor compositions, including butter, milk, cream, and cheese. Diacetyl was found to be mutagenic in Ames test conducted under various different conditions with Salmonella typhimurium strains. For example, diacetyl was mutagenic by TA100 in the absence of S9 metabolic activation at doses up to 40 mM/plate. It was mutagenic in a modified Ames assay in Salmonella typhimurium strains TA100 with and without S9 activation. The acute oral LD50 of diacetyl in guinea pigs was calculated to be 990 mg/kg. The acute oral LD50 of diacetyl in male rats was calculated to be 3400 mg/kg, and in female rats, the LD50 was calculated to be 3000 mg/kg. When male and female rats were administered via gavage a daily dose of 1, 30, 90, or 540 mg/kg/day of diacetyl in water for 90 days, the high-dose produced anemia, decreased weight gain, increased water consumption, increased leukocyte count, and an increase in the relative weights of liver, kidneys, and adrenal and pituitary glands. The data for teratogenicity and carcinogenicity are not available. Although the FDA has affirmed diacetyl GRAS as a flavoring agent, low molecular weight carbonyls, such as formaldehyde, acetaldehyde, and glyoxal have been reported to possess a certain chronic toxicity.

純化方法

Dry biacetyl over anhydrous CaSO4, CaCl2 or MgSO4, then distil it in a vacuum under nitrogen, taking the middle fraction and storing it at Dry-Ice temperature in the dark (to prevent polymerization). [Beilstein 1 IV 3644.]
