Abstract: The present disclosure relates to methods for preparing materials from heavy feedstocks. In particular, the disclosure provides a chemical process to convert heavy feedstocks with predominant polyaromatic hydrocarbon molecules or species, including the residues of petrochemical refining or extraction, into thermoset or thermoplastic materials that can be used alone or as a component in a composite material.

Abstract: This disclosure relates to the preparation of diphenyl compounds, especially dimethylbiphenyl compounds, in which there is one methyl group on each ring, and their oxidized analogues. These compounds, and particularly alkylated biphenyl compounds and biphenylcarboxylic acids, alcohols and esters, are useful intermediates in the production of a variety of commercially valuable products, including polyesters and plasticizers for PVC and other polymer compositions.

Abstract: A process for making a silica-polyolefin composite. The process has the steps of (a) reacting silica particles and an alkyl halosilane in the presence of a solvent and a catalyst to form silane-functionalized silica particles and (b) reacting the silane-functionalized silica particles with a vinyl-terminated polyolefin. There are other processes for making a silica-polyolefin composites. There are other processes for making metal phosphate-polyolefin composites.

Abstract: A process for selective oxidation of dimethyl-1,1′-biphenyl to form methyl-1,1′-biphenyl mono-carboxylic acid(s), comprising contacting a solution of dimethyl-1,1′-biphenyl in acetic acid solvent in the presence of a Co(II) acetate catalyst and air, and optionally adding a co-solvent, or adding sodium or potassium acetate, and oxidizing the dimethyl-1,1′-biphenyl under time and temperature conditions sufficient to form one or more methyl-1,1′-biphenyl mono-carboxylic acid(s). The mono-carboxylic acids are advantageously isolated and esterified to form biphenyl mono-esters for use as plasticizers.

Abstract: A process for selective oxidation of dimethyl-1,1′-biphenyl(s) to form methyl-1,1′-biphenyl mono-carboxylic acid(s), which can be esterified to form plasticizers, comprising contacting a solution of dimethyl-1,1′-biphenyl(s) in acetic acid in the presence of an oxidation catalyst and air under time and temperature conditions sufficient to oxidize the dimethyl-1,1′-biphenyl(s) into one or more methyl-1,1′-biphenyl mono-carboxylic acid(s) products, conducting at least one of (i) adding an antisolvent, or (ii) optimizing a total conversion of dimethyl-1,1′-biphenyl(s) by oxidation based upon a molar ratio of dimethyl-1,1′-biphenyl isomers, or (iii) precipitating the methyl-1,1′-biphenyl mono-carboxylic acid(s) products by lowering the temperature, or (iv) decreasing the oxidation reaction temperature to enhance conversion of aldehydes over methyl functional groups, so as to limit over-oxidation of the dimethyl-1,1′-biphenyl(s), wherein the oxidation reaction is conducted in the absence of bromide-containing catalysts.
