Disclosed is a very economical way to produce vinyl carbonyls such as ethyl vinyl ketone. Disclosed also is a purification process of separating vinyl carbonyls and coreactants. The catalyst and reaction conditions give useful yields of vinyl carbonyls, the thermodynamically unfavorable product along with coreactants that are more thermodynamically favored. Disclosed also is the separation of reactants that takes place at low distillation temperatures and pressures in the presence of antioxidant.
