Acetone - Wikipedia, the free encyclopedia (828 words)
Acetone is also used as a drying agent, due to the readiness with which it binds to water, and its volatility.
Acetone is particularly useful because it is inexpensive, is moderately polar allowing it to dissolve a wide range of organic substances, and evaporates quickly.
Acetone is an irritant and inhalation may lead to hepatotoxic effects (causing liver damage).
acetone: Definition and Much More from Answers.com (1119 words)
Acetone melts at −94.8°C and boils at 56.2°C. It is the simplest aliphatic ketone.
Acetone is widely used in industry as a solvent for numerous organic substances and is a component of most paint and varnish removers.
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).
