Acetone (2-propanone), CH 3-CO-CH 3, is a clear colorless liquid with a characteristic fruity and sweetish odor. It is flammable and vapors are heavier than air. Acetone is toxic in high doses. Acetone occurs naturally in plants, trees, forest fires, vehicle exhaust and as a breakdown product of animal fat metabolism.
