Rate enhancing of carbon dioxide in the reaction of acetonitrile with methanol to acrylonitrile over magnesium oxide catalyst

Article abstract of DOI:10.1246/cl.1995.793

Carbon dioxide greatly enhanced the formation of acrylonitrile in the gas-phase reaction of acetonitrile with methanol over magnesium oxide catalyst.The reaction in the presence of carbon dioxide was accompanied by the reaction of methanol with carbon dioxide to give carbon monoxide and water.An adsorbed carbon dioxide species on the basic surface of magnesium oxide seems to afford an active methanol-derived species for the reaction with acetonitrile.
