Uses of Acetone
It is a colourless, volatile, flammable organic solvent which occurs naturally in trees, vehicle exhaust, plants and as a breakdown product of animal fat for metabolism. It has a sweetish (fruity) odour. The molecular formula for the compound is CH3-CO-CH3 or CH3COCH3 or C3H6O. Other names that identify the chemical are 2-propanone, dimethyl ketone, and beta ketopropane. It dissolves in water, is toxic in high doses, is the simplest ketone. Its vapours are denser than air and it has a flash point of 0 degrees Fahrenheit. It has a boiling point of 133 degrees Fahrenheit at 760mm Hg (NTP, 1992) and a melting point of 137 degrees Fahrenheit (NTP, 1992). Its solubility is greater than or equal to 100mg/ml at 72 degrees Fahrenheit (NTP, 1992).
