Oxidation of butene to maleic anhydride--1. Kinetics and mechanism
Product analyses of the air oxidation of butene (53.8Vertical Bar3< trans-2-butene, 41.1Vertical Bar3< cis-2-butene, balance 1-butene) on vanadyl phosphate (1.6:1 phosphorus/vanadium) supported on silica in a practically isothermal catalyst bed at 350/sup 0/-390/sup 0/C and at Vertical Bar3; 1Vertical Bar3< butene in the feed showed that the reaction proceeded by a two-step redox mechanism involving a vanadium(IV) 1 vanadium(V) cycle, that the reaction was first order in butene, and that maleic anhydride formed via butadiene without significant decomposition to carbon oxides. The kinetic parameters of the reaction steps of butene to butadiene, butadiene to maleic anhydride, and butene and butadiene to carbon oxides were determined.
