ELECTRON ACCEPTOR COMPOSITIONS ON POLYMER TEMPLATES AND CATALYTIC PRODUCTION OF HYDROGEN PEROXIDE

摘要

A catalytic process for producing hydrogen peroxide from oxygen and hydrogen comprising the steps of: A) treating an aqueous suspension of heterogeneous catalyst with a source of oxygen and a source of hydrogen; B) separating the catalyst; and, C) isolating the produced hydrogen peroxide, wherein said catalyst is a complex of the formula: wherein each of Y<1>, Y<2>, and Y<3>, independently of the other, is phosphorus or arsenic; Z is a divalent group which reversibly forms a stable reduced form, said group containing two conjugated cationic centers which together have a negative Ered value; Me<2> is a trivalent or tetravalent metal of Group III, IVA, or IVB having an atomic number of at least 21 or a lanthanide; X is anion; n has a value of from 0 to 0.8; and p has a value of 1, 2 or 3; and R<3> is a nonreducible capping group.
