This disclosure relates to ester compounds formed from gamma-branched aliphatic alcohols, lubricating oil base stocks comprising such ester compounds, lubricating oil compositions comprising such ester compounds, and method of making such base stocks. The lubricating oil base stocks comprising the ester compounds exhibit desirable lubricating properties such as polarity.

The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

Synthesis of succinimides and quaternary ammonium ions for use in making molecular sieves

This disclosure relates to methods for producing purified aromatic esters useful as plasticizers, to the purified aromatic esters, and to polymer compositions containing the purified esters. The purified aromatic esters can be produced by esterifying carboxylic acid with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying the methyl or ethyl esters with Cto Calcohol to produce the purified aromatic esters. Additionally, precipitation, filtration, and wash steps can be employed to purify the carboxylic acid, the methyl or ethyl alcohol, and/or the aromatic esters.

Purified plasticizers, production and use

A process for selective oxidation of dimethyl-1,1'-biphenyl to form methyl-1,1&#x2032;-biphenyl mono-carboxylic acid(s), comprising contacting a solution of dimethyl-1,1&#x2032;-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&#x2032;-biphenyl under time and temperature conditions sufficient to form one or more methyl-1,1&#x2032;-biphenyl mono-carboxylic acid(s). The mono-carboxylic acids are advantageously isolated and esterified to form biphenyl mono-esters for use as plasticizers.

Selective aerobic oxidation of dimethylbiphenyls

A process for selective oxidation of dimethyl-1,1'-biphenyl(s) to form methyl-1,1&#x2032;-biphenyl mono-carboxylic acid(s), which can be esterified to form plasticizers, comprising contacting a solution of dimethyl-1,1&#x2032;-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&#x2032;-biphenyl(s) into one or more methyl-1,1&#x2032;-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&#x2032;-biphenyl(s) by oxidation based upon a molar ratio of dimethyl-1,1&#x2032;-biphenyl isomers, or (iii) precipitating the methyl-1,1&#x2032;-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&#x2032;-biphenyl(s), wherein the oxidation reaction is conducted in the absence of bromide-containing catalysts.

A composition including one or more monomethyl ester compounds represented by the formula: Ris a monomethyl branched Cto Calkyl group and Ris an unsubstituted Cto Clinear alkyl group.
