What is Methyl Ethyl Ketone (Butanone)?
Methyl Ethyl Ketone is an organic compound which is also known as Butanone or Methylacetone. It is a dialkyl ketone which consists of 4 carbon ketone that carries a single keto group at the C-2 position. It acts as a bacterial metabolite and polar aprotic solvent.
Properties of Methyl Ethyl Ketone
Butanone is a colourless, volatile liquid and has a pleasant pungent smell. The flash point of MEK is 20°F. The vapours formed are heavier than air. It dissolves in water. It is obtained as a natural product. It is present in some vegetables and fruits in small quantities. Also, it is released from truck and car exhausts.
