Catalytic oxidative dehydrogenation of n-butane at 550-650° over Mo and/or W oxide contg. at least one of the oxides of Cr, Mn, Fe, Ni, or Cd gave ∼5 wt. % n-butenes and 10-20 wt. % butadiene. Thus, addn. of Ni(NO3)3 in H2O to (NH4)6Mo7O24 in H2O and heating the ppt. at 400-500° gave a catalyst with 1:2 Mo-Ni at. ratio. n-Butane, O, and H2O vapor at a 1:0.25:10 molar ratio and 590° reacted in the presence of 15 ml catalyst to give 4.5 wt. % n-butanes and 21 wt. % butadiene.
