Abstract
A process is provided for the preparation of iron phosphorous mixed oxide catalysts which are highly active at moderate temperatures by introducing iron and phosphorus containing compounds and promoter element containing compounds, if any, into a substantially organic liquid medium, heating, separating the resulting precursor, drying and calcining. The catalysts are useful for the dehydrogenation or oxydehydrogenation of organic compounds such as aldehydes or carboxylic acids.
