A composition for the destruction of chemical warfare agents and toxic industrial chemicals having a polyoxometalate (POM) attached to an amine, carboxylic acid, or ammonium substituted porous polymer. Also disclosed is a method for attaching a POM to an amine, carboxylic acid, or ammonium substituted porous polymer by (1) dissolving the POM in water or an organic solvent, adding the functionalized porous polymer, whereby the POM ionically attaches to the amine, carboxylic acid or ammonium group, or (2) heating the POM and functionalized polymer in the presence of a dehydrating agent whereby an imide bond is produced between the POM and the functionality on the porous polymer.

The present invention relates to a catalyst containing a vanadium-phosphorus oxide and an alkali metal, wherein the proportion by weight of alkali metal in the vanadium-phosphorus oxide is in the range from 10 to 400 ppm, based on the total weight of the vanadium-phosphorus oxide, a process for producing it and also the use of the catalyst for the gas-phase oxidation of hydrocarbons, in particular for preparing maleic anhydride.

The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus modified with alkali metal. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed.

A catalyst for treating heavy hydrocarbon feedstocks. The catalyst comprises a calcined particle comprising a co-mulled mixture made by co-mulling inorganic oxide powder, molybdenum trioxide powder, and a nickel compound or cobalt compound, or both compounds, and then forming the co-mulled mixture into a particle that is calcined to provide the calcined particle. The calcination is conducted at a temperature such that at least 20% of the pore volume of the calcined particle is in pores of greater than 5,000 ? and less than 70% of the pore volume of the calcined particle is in the pores having a pore size in the range of from 70 to 250 ?.
