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.

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 reforming catalyst with improved surface area is provided by using high surface area alumina doped with a stabilizer metal as a catalyst support. The surface area of the catalyst can be higher than a typical reforming catalyst, and the surface area can also be maintained under high temperature operation. This can allow use of the catalyst for reforming in a higher temperature environment while maintaining a higher surface area, which can allow for improved dispersion and/or activity of an active metal such as rhodium on the catalyst support. The catalyst can be suitable for production of syngas from natural gas or other hydrocarbon-containing feeds.

Abstract: In a process for the catalytic alkylation of an olefin with an isoparaffin, an olefin-containing feed is contacted with an isoparaffin-containing feed under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework types, wherein the olefin-containing feed consists essentially of pentenes.
