Catalyst comprising a combination of oxidized metals and processes for cleaving phenylalkyl hydroperoxides in the presence of the catalyst.

Catalysts comprising a combination of oxidized metals and a method for cleaving phenylalkyl hydroperoxides using the catalysts

A method for increasing selectivity of alkylation to monoalkylation comprising: providing a feedstream consisting essentially of alkylating agent and a stoichiometric excess of benzene, the alkylating agent consisting essentially of a molar blend of propylene and one or more linear butene(s); and, contacting the feedstream with a catalytically effective amount of zeolite beta under alkylation reaction conditions which increase selectivity of the alkylation to monoalkylation compared to predicted selectivity to monoalkylation based on the concentration of the alkylating agent and on the molar blend of propylene and one or more linear butene(s).

Selective alkylation of aromatic hydrocarbons

An oxidation free process for converting a hydroxy substituted aromatic to an aromatic diacid which comprises reacting a hydroxy substituted aromatic with excess basic salt in the presence of carbon dioxide at disproportionation/isomerization reaction conditions.

Process for producing diacids by carboxylation of phenolic compounds

Polyketone polymers are cured by exposure to high energy radiation. Radiation sources include gamma radiation sources such as Co.sup.60 emitters as well as e-beam, ion and other commercially used sources of high energy radiation. The materials so produced are high molecular weight crosslinked polyketone polymers which exhibit enhanced mechanical and tribological properties.

Curing polyketones with high energy radiation

Relatively low molecular weight Olefin/CO copolymers are graft copolymerized with vinyl monomers by the exposure of a mixture of a dispersion of the two to high energy radiation such as .gamma. ray radiation. Styrene is an example of a monomer useful in forming the graft copolymer. The graft copolymers are useful as waterborne glues particularly in the preparation of wood composites.
