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. ==References== <references/> ==External links== *[http://www.state.nj.us/health/eoh/rtkweb/1301.pdf#search=%22%22methyl%20vinyl%20ketone%22%22 NJ Hazardous Substance Factsheet for methyl vinyl ketone] *[http://www.mathesontrigas.com/pdfs/msds/MAT14770.pdf#search=%22MSDS%20%22methyl%20vinyl%20ketone%22%22 MSDS for methyl vinyl ketone] [[Category:Alkenes]] [[Category:Alkylating agents]] [[Category:Ketones]] [[es:Metil vinil cetona]] [[fi:Metyylivinyyliketoni]] [[ja:メチルビニルケトン]]
