'''Methyl vinyl ketone''' (MVK) is a reactive organic compound classified as an [[enone]]. It is a colorless, flammable, highly toxic liquid with a pungent odor. It is easily soluble in water, [[methanol]], [[ethanol]], [[acetone]], and [[acetic acid]].
MVK has been prepared industrially by the [[condensation reaction|condensation]] of acetone and [[formaldehyde]], followed by [[dehydration reaction|dehydration]].
MVK can act as an [[alkylating agent]] because it is an effective [[Michael reaction|Michael acceptor]]. Its alkylating ability is both the source of its high toxicity and the feature that makes it a useful intermediate in [[organic synthesis]]. MVK will [[polymerization|polymerize]] spontaneously, and is used in the manufacture of plastic [[polymer]]s. It is also an intermediate in the synthesis of [[steroid]]s and [[vitamin A]].
MVK is extremely hazardous upon inhalation causing coughing, wheezing and shortness of breath even at low concentrations. It will also readily cause irritation of the skin, eyes, and mucous membranes.
