Acetoin Chemical Properties,Uses,Production
Chemical Properties
Acetoin is a yellowish liquid with a bland, woody, yogurt odor and a fatty creamy “tub” butter taste. It is useful as a flavor ingredient in butter, milk, yogurt or strawberry flavors.
Occurrence
Reported found in fresh apple, butter, cheddar cheese, coffee, cocoa, honey, wheat bread and wine
Uses
Acetoin is a produced via fermentation of wines, dairy products and sugars by fermentive bacteria. Acetoin is used in food flavoring and fragrances and is also found in some fruits and vegetables.
Definition
ChEBI: A methyl ketone that is butan-2-one substituted by a hydroxy group at position 3.
General Description
A light-yellow colored liquid. Slightly denser than water. Hence sinks in water. Boiling point 280°F. Flash point between 100 and 141°F. Used to make other chemicals.
Air & Water Reactions
Flammable. Slightly soluble in water.
Reactivity Profile
3-Hydroxy-2-butanone is a ketone and alcohol. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Health Hazard
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.
Fire Hazard
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.
Safety Profile
Experimental reproductive effects. LWdly toxic by subcutaneous route. A moderate skin irritant. Flammable liquid. When heated to decomposition it emits acrid smoke and fumes. See also KETONES
Purification Methods
Wash acetoin with EtOH until colourless, then with diethyl ether or acetone to remove biacetyl. Dry it in air by suction and dry further in a vacuum desiccator. [Beilstein 1 IV 3991.]
