Abstract
Compositions having a host phase of a niobate or tantalate of a divalent or trivalent metal and containing vanadium from one atom present to the limit of solid solubility in the host phase. Host phases of the rutile, columbite and trirutile structure are disclosed. The compositions are useful in the partial oxidation and ammoxidation of lower alkanes.
Claims16
A method for producing oxidation products selected from the group consisting of alcohols, aldehydes, ketones and mixtures thereof from alkanes, comprises reacting an alkane at elevated temperatures within the range from about 300.degree. C. to 600.degree. C. with oxygen in the presence of a catalyst comprising a host-phase selected from the group consisting of niobates and tantalates of divalent and trivalent metals and containing vanadium from about 1 atom percent to the limit of solid solubility in the host phase.
