Basic Info

3-Pentanone (also known as diethyl ketone) is a simple, symmetrical dialkyl ketone. It is a colorless liquid ketone with an odor like that of acetone. It is soluble in about 25 parts water, but miscible with organic solvents. It is mainly used as a solvent in paint and a precursor to vitamin E. It is easily soluble in diethyl ether and partially soluble in acetone, methanol, and water. Two related and more important ketones are 2-pentanone and methyl isopropyl ketone.
