    Abstract: A catalyst composition represented by the formula
    wherein A is selected Cd, Cr, Ge, Te, Th, Ti, U, V, Zr, rare earths and mixtures thereof; wherein D is selected from Ag, Cu, Mn and mixtures thereof; and wherein

    a = 0-1.0
    b = 0.75-1.5
    c = 1.0-2.0
    d = 0-2.0
    a + d is greater than zero and
    x is the number of oxygens needed to satisfy the valence requirements of the remaining elements.

    This catalyst is particularly suitable for the oxydehydrogenation of saturated carboxylic acids, such as isobutyric acid, to form alpha, beta unsaturated carboxylic acids, such as methacrylic acid.

    Abstract: A process for preparing a supported solid oxide complex catalyst using silica as support characterised in that one adds fumed silica to a mixture containing one or more active components of the catalyst; dries said mixture to form a dried first-stage mixture; adds, in solution. silica or a silica-containing compound other than fumed silica to the dried first stage mixture optionally with further fumed silica; and dries and calcines the resulting mixture is provided.
    The use of fumed silica produces a supported solid oxide complex catalyst of increased attrition resistance. Such catalyst is useful in the preparation of unsaturated aldehydes and acids from propylene or isobutylene by vapour phase oxidation. The use of inert or recycle gas increases the performance of such catalyst in this reaction.
