Abstract

Direct formation of methacrolein from isobutene was studied using a combination of the catalyst effective for oxidative dehydrogenation of isobutene, Ni2P2O7, and the catalyst effective for selective oxidation of olefins, Bi-Mo12-Fe-Co6-Ni2Cs0.1 4-oxide. Methacrolein was formed with the selectivity as high as 65% in a reactor with two catalyst beds in series. A catalyst consisting of a mixture of the powders of both catalysts was effective for isobutene formation, although the conversion was reduced, whereas a mixture of granules was less effective. Addition of water vapor to the reaction system reduced the formation of oxygenates and promoted the formation of isobutene.
