Butanone - Wikipedia

Butanone Butanone, also known as methyl ethyl ketone ( MEK ), [a] is an organic compound with the formula CH 3 C (O)CH 2 CH 3. This colourless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts. [7]
