In chemistry, acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and beta-ketopropane) is the simplest representative of the ketones.

Acetone is a colorless mobile flammable liquid with melting point at -95.4 °C and boiling point at 56.53 °C. It has a relative density of 0.819 (at 0 °C). It is readily soluble in water, ethanol, ether, etc., and itself serves as an important solvent. The most familiar household use of acetone is as the active ingredient in nail polish remover. Acetone is also used to make plastic, fibers, drugs, and other chemicals.

An important industrial use for acetone involves its reaction with phenol for the manufacture of bisphenol A. Bisphenol A is an important component of many polymers such as polycarbonates, polyurethanes and epoxy resins. Acetone is also used extensively for the safe transporting and storing of acetylene. Vessels containing a porous material are filled with acetone then acetylene, which dissolves into the acetone. One liter of acetone can dissolve around 250 liters of acetylene.

Acetone is often the primary (or only) component in nail polish remover. Acetone is also used as a superglue remover. Small quantities of acetone added to fuel may improve economy and engine performance, though this is only anecdotal and refuted by most automotive engineers.

Acetone has been used in the manufacture of TNT. During World War I a new process of producing acetone through bacterial fermentation was developed by Chaim Weizmann, to help the British war effort.

Acetone can result in unconsciousness and damage to the skin in the mouth. Skin contact can result in irritation and damage to the skin. If you inhale it for long periods of time, it is dangerous.

The smell and respiratory data are known mostly from animal studies. Kidney, liver, and nerve damage, increased birth defects, and lowered reproduction ability of males (only) occurred in animals exposed long-term. It is not known if these same effects would be exhibited in humans.

Interestingly, acetone has been shown to have anticonvulsant effects in animal models of epilepsy, in the absence of toxicity, when administered in millimolar concentrations (see: Likhodii et al, 2003).
