Methyl Ethyl Ketone - C4H8O

What is Methyl Ethyl Ketone (Butanone)?

Methyl Ethyl Ketone is an organic compound which is also known as Butanone or Methylacetone.

Methyl Ethyl Ketone 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 flashpoint 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.

Frequently Asked Questions

What is methyl ethyl ketone used for?

MEK is a liquid solvent used in surface coatings, adhesives, inks for printing, chemical intermediates, magnetic tapes and dewaxing lube oil. MEK is also used as a tool for extraction of fats, oils, waxes and resins. For surface coatings it is a highly effective and flexible solvent.

Is methyl ethyl ketone the same as acetone?z

MEK, also known as Butanone and Methyl Ethyl Ketone, is an acetone-related solvent, since acetone is actually liquid ketone.

How is methyl ethyl ketone produced?

MEK is an herbal, colorless liquid with an odor similar to acetone. MEK is produced in the US using secondary butyl alcohol dehydrogenation (approximately 86%) and as a by-product of butane oxidation (remaining 14%).

Is MEK miscible with water?

Methyl ethyl ketone, MEK, a low-boiling, rapidly evaporating solution, is a methyl ethyl ketone, MEK, a low-boiling, rapidly evaporating, colorless, inert liquid, partially water miscible.

What is MEK made of?

Butanone is an organic compound containing the formula CH3C(O)CH2CH3, also known as methyl ethyl ketone (MEK). This colorless liquid ketone has a sharp, sweet butterscotch and acetone-reminiscent odour. It is industrially manufactured on a large scale, and also occurs in nature in trace quantities.
