Methyl vinyl ether is an organic compound with the chemical formula C3H6O. It is the simplest chemical that contains both an alkene group and an alkyl group with an ether linkage. The compound can be made by reaction of acetylene and methanol in presence of a base. ; The alkene portion of the molecule is reactive in many ways. It is prone to polymerization, leading to formation of poly(methyl vinyl ether) (PMVE, CAS: 9003-09-2). This mode of reactivity is analogous to the way vinyl acetate and vinyl chloride can be polymerized to form polyvinyl acetate and polyvinyl chloride, respectively. The alkene can also react in [4+2] cycloaddition reactions. The reaction of it with acrolein is the first step in the commercial synthesis of glutaraldehyde.
