Abstract

Method termoprogramirovannoy desorption (TPD) of oxygen was studied the state of oxygen on the surfacemodified vanadium catalysts. Found that the introduction of phosphorus into the catalyst promotes vanadiymolibdenovogo fraction of adsorbed oxygen participating in the oxidation of benzene to maleic anhydride.
