3-Methyl-2-butanone Usage And Synthesis
CLEAR COLOURLESS LIQUID
MIPK is a colorless liquid with an acetonelike odor.
Methyl isopropyl ketone (MIPK) is used asa solvent for lacquers.
Solvent for nitrocellulose lacquers.
A colorless liquid with a pleasant odor. Flash point below 70°F. Less dense than water. May be toxic by inhalation and skin absorption. Used as a solvent.
Air & Water Reactions
Highly flammable. Soluble in water.
Ketones, such as 3-Methyl-2-butanone, 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.
Toxic material. Embryo/fetal damage andneonatal toxicity.
Irritating to the eyes, nose, throat, upper respiratory tract, and skin.
The acute toxic effects from exposure to thevapors of MIPK are narcosis and irritationof the eyes, skin, and respiratory passages.In rabbits the irritation effect of 100 mg fora 24-hour exposure was mild in the eyes,while 500 mg was moderate on the skin. Thetoxicity data on this compound are too scant.In general, its toxicity is low and narcosissymptoms in humans may be felt only at veryhigh concentrations. In guinea pigs exposureto 5000 ppm caused coma.
Special Hazards of Combustion Products: Acrid smoke and fumes
Poison by ingestion. Mildly toxic by inhalation and skin contact. Mutation data reported. A skin and eye irritant. Flammable when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes.
This ketone is used as a solvent for nitrocellulose lacquers.
UN23973-Methylbutan-2-one, Hazard Class: 3; Labels: 3-Flammable liquid.
Reflux the ketone with a little KMnO4. Fractionate it through a spinning-band column, dry with CaSO4 and distil it. [Beilstein 1 IV 3287.]
Vapors may form explosive mixture with air. Ketones are 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, nitrated amines, azo, diazo, azido compounds, carbamates, organic cyanates
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.
