Abstract: The production of acrylates and methacrylates, made by the oxidative esterification of propylene or isobutylene wherein gaseous reactants are contacted with one or more catalysts and ethylene or an alcohol can be advantageously conducted in a single fluid bed reactor to obtain the desired ester.

Abstract: Maleic anhydride is prepared by reacting n-butene with molecular oxygen at a temperature of about 200 DEG to about 600 DEG C in a fluid-bed reactor using a catalyst charge containing two different catalysts--the first catalyst being one that is especially effective for preparing butadiene from the n-butylenes; and the second catalyst being one that is especially effective for preparing maleic anhydride from butadiene. Unexpectedly, substantial yields of maleic anhydride are obtained.
