ABSTRACT:
Sacrificial use of amino polymers to modify the crystal structure of platinum derived from chlorine compounds in a method to oxidize hydrocarbons, comprising: (a) preparing a polymer modifier by controllably reacting amine with epoxy resin to form a soluble adduct and adding to the adduct a solvent to form a homogeneous amino polymer solution; (b) coating a granular support material with platinum/chlorine compounds; and (c) mixing the coated support material with the polymer solution and heating the mixture to evaporate the solvent and to decompose and eliminate the polymer, leaving the coated granules with platinum in a morphologically changed condition devoid of amino polymer but having enhanced catalytic effectiveness for promoting oxidation of hydrocarbons. The amine is of a primary or secondary amine, preferably the hydroxyethyl group. The epoxy is a soluble resin comprising two or more epoxide groups per molecule, i.e., dihydric phenol or dihydric alcohol. The polymer modifier is preferably a soluble amino polymer having a molecular weight of 500-50,000 and advantageously is 50% or more by weight of the solution.
