The present invention relates to a process for producing a mixture that is insoluble in water of a homologous series of a number of various long-chain (C.sub.8) alkyl dicarboxylic acids, more particularly ,-n-alkyl dicarboxylic acids, by oxidative degradation of polyethylene (PE)-containing mixtures with oxygen, and to the mixtures or compositions obtainable therefrom and to their uses.

The present invention relates to a supported anthraquinonic catalyst which may be obtained by radical polymerization of a reaction mixture comprising styrene; at least one initiator generating free radicals; at least one cross-linking agent which is at least difunctional, at least one pore-forming agent; and at least one anthraquinonic styrenic monomer of formula (I)

##STR00001## wherein n is an integer varying from 1 to 5.

The present invention is related to processes for preparing antiviral prodrugs, co-crystals, solvents, salts or combinations thereof, and related synthetic intermediate compounds.

Provided are a catalyst loaded with a TEMPO-type compound, and a preparation method and use thereof. The catalyst loaded with the TEMPO-type compound uses a polymer resin as a carrier, and the polymer resin is a polystyrene resin containing a chloromethyl or bromomethyl, herein the content of the chloromethyl or bromomethyl in the polymer resin is 0.5-5.0 mmol g.sup.1.

Disclosed herein is a catalytic comprising a hexacyano metal compound; wherein the hexacyano metal compound comprises a metal selected from the group consisting of cobalt, iron, copper, manganese, nickel, zinc, and combinations thereof; wherein the hexacyano metal compound comprises coordinatively unsaturated metal (II)NC centers for; and wherein the hexacyano metal compound is anchored onto an inorganic substrate. Also disclosed are a system including the catalytic material and a process for treating wastewater using the catalytic material.
