ACETONE
Acetone is clear, colorless, low boiling, flammable, volatile, liquid, characterized by rapid evaporation and a faintly aromatic, sweetish odor. It is readily miscible in most organic solvents and completely miscible, in all proportions, in distilled water. It is widely used as a chemical intermediate in the production of methyl isobutyl ketone and other solvents, and in the production of such important chemicals as bisphenol A and methyl methacrylate. It is also used in the manufacture of a wide variety of coatings and plastics.
