General Description
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.
Reactivity Profile
Ketones, such as 3-METHYLBUTAN-2-ONE(563-80-4), 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.
Air & Water Reactions
Highly flammable. Soluble in water.
Hazard
Toxic material. Embryo/fetal damage andneonatal toxicity.
Health Hazard
Irritating to the eyes, nose, throat, upper respiratory tract, and skin.
Potential Exposure
This ketone is used as a solvent for
nitrocellulose lacquers.
Fire Hazard
Special Hazards of Combustion Products: Acrid smoke and fumes
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit

Incompatibilities
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

storage
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Before entering confinedspace where this chemical may be present, check to makesure that an explosive concentration does not exist. Store intightly closed containers in a cool, well-ventilated areaaway from aldehydes. Sources of ignition, such as smokingand open flames, are prohibited where methyl isopropylketone is used, handled, or stored in a manner that couldcreate a potential fire or explosion hazard. Use only nonsparking tools and equipment, especially when opening andclosing containers of methyl isopropyl ketone. Wherevermethyl isopropyl ketone is used, handled, manufactured, orstored, use explosion-proof electrical equipment andfittings.
Purification Methods
Reflux the ketone with a little KMnO4. Fractionate it through a spinning-band column, dry with CaSO4 and distil it. [Beilstein 1 IV 3287.]
