VERFAHREN ZUR HERSTELLUNG VON MALEINSAEUREANHYDRID

Ethylenically unsaturated C4-n-hydrocarbons are oxidized to maleic anhydride by passing a stream of oxygen-containing gas at high temperature over a catalyst of the formula WaMobSbcYdXeOx wherein Y=P, Si; X=V, Bi, Te, alkali metal; a and b each =1-12; c=2-20; d=0.2-2; e=0-10; and x is the number of...
