Methyl vinyl ether
Methyl vinyl ether is an organic compound with the chemical formula CH3OCH=CH2.It is used as a synthetic building block, as is the related compound ethyl vinyl ether (a liquid at room temperature).Methyl vinyl ether can be made by reaction of acetylene and methanol in presence of a base.[6] In particular, this approach allows the synthesis of a variety of acyl derivatives of silicon, germanium, and tin that cannot be made easily by other routes.The acute LD50 for methyl vinyl ether is greater than 4 g/kg (rats, oral).
