A process is provided for the preparation of coated iron phosphorus oxide containing catalysts useful in the oxydehydrogenation of saturated carboxylic acids, wherein the catalysts are prepared by partially wetting a carrier or support in an aqueous silica solution/suspension, contacting the partially wet carrier with a powder of the iron phosphorus oxide catalyst, drying and calcining.

Oxidative dehydrogenation of carboxylic acids with mixed metal

A process for preparing a metal oxygen composition capable of dehydrocoupling toluene wherein metal oxides such as Sb.sub.2 O.sub.3, PbO, and Bi.sub.2 O.sub.3 are admixed with an organic media such as isobutanol and heated to form a metal oxygen precursor composition which is recovered and calcined is disclosed.

Process for preparing inorganic metal oxygen composition capable of

A process for dehydrocoupling a hydrocarbon, such as toluene, using oxygen as the oxidant, in the presence of a crystalline zeolite of the faujasite structure containing a cation such as cesium, and a promoter, such as boron and/or phosphorus is disclosed.
