The air oxidation of isobutene was investigated over supported and unsupported copper oxide catalysts in an isothermal integral flow reactor. The effect of various variables, that is, ratio of oxygen to isobutene in the feed, process temperature, copper concentration on the catalyst and reciprocal of space velocity on the conversion and yield were determined. Though several mechanisms were postulated, the rate of reaction was most satisfactorily correlated by a mechanism which assumes the rate controlling step as the surface reaction between strongly adsorbed isobutene and gaseous (weakly adsorbed) oxygen. A rate equation has been derived and the kinetic rate constant and adsorption constants for isobutene and methacrolein are reported as functions of temperature.
