ABSTRACT:
Maleic anhydride is prepared by reacting n-butene with molecular oxygen at a temperature of about 200.degree. to about 600.degree. 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.
