Yellow to yellow-green liquid, after a large amount of dilution (at 1mg/kg), it has a creamy aroma. The vapor pressure is high, and it can evaporate quickly at room temperature. Melting point -3～-4℃, boiling point 87～88℃, flash point 13℃. It is miscible in ethanol, ether, most non-volatile Chemicalbook hair oils and propylene glycol, soluble in glycerin and water, but insoluble in mineral oil. Natural products are found in bay oil, celery oil, root oil of Angelica dahurica, raspberry, strawberry, cream, wine and so on. Because it is volatile, it only exists in the first fraction of essential oils and distilled water.

Production method:
- In nature, diacetyl is widely found in the essential oils of many plants, such as iris oil, angelica oil, laurel oil, etc., and is the main component of butter and other natural product fragrances. Industrial production of butanedione is obtained by treating methyl ethyl ketone with nitrous acid Chemicalbook to generate butanone oxime and then decomposing it with dilute sulfuric acid. Or use vinyl acetylene or methyl vinyl ketone through hydration and reoxidation. The laboratory can use selenium dioxide to oxidize butanone to prepare it, and also use the method of reacting diketone dioxime with sodium nitrite.
- It can be prepared from the high content of essential oil by free method: 1 part of essential oil plus 2 parts of phosphoric acid to form a crystalline adduct C4H6O2? 2H3PO4. After adding water, diacetyl is released. If phosphoric acid is added to Chemicalbook in excess, the adduct Is liquid. Obtained from glucose through special fermentation. Synthesize with methyl ethyl ketone as starting material. The methyl ethyl ketone is oxidized with sodium nitrite in the presence of hydrochloric acid, hydrolyzed with sulfuric acid and then distilled.
