    Abstract: A method of purifying a stream having an aromatic carboxy-aldehyde and an aromatic acid or the corresponding anhydride is described. The method includes reacting a hydroxylamine-containing compound with the aromatic carboxy-aldehyde in the stream to form a reaction mixture including the corresponding nitrone; adding an aqueous solvent to the reaction mixture, in an amount and under conditions effective to solubilize the nitrone but not the organic acid or the corresponding anhydride; and separating the solubilized nitrone from the non- solubilized organic acid. The nitrone is a water soluble nitrone.

    Abstract: An unleaded gasoline composition comprises, based on the total volume of the unleaded gasoline composition, 50 to 96 vol.% of an unleaded gasoline; 2 to 20 vol.% of a mixed butanol; and 2 to 30 vol.% of a distillate oil fraction comprising a paraffin, an olefin, a naphthene, and an aromatic at an initial boiling point cut of 180°C, wherein the unleaded gasoline, the mixed butanol, and the distillate oil fraction are selected to provide the unleaded gasoline composition with a Research Octane Number of 90 to 101, determined in accordance with ASTM D 2699; and a Motor Octane Number of 81.4 to 90, determined in accordance with ASTM D 2700.

    Abstract: A process for preparing fatty acids includes: forming a crude fatty acid product by splitting a feedstream comprising oils and/or fats in a splitting column; fractioning the crude fatty acid product into a short chain fatty acid stream, a long chain fatty acid stream, and a residual product stream in a fractionating distillation column; mixing the short chain fatty acid stream with a whitening compound during distillation in a first distillation column, forming an intermediate short chain fatty acid stream; and purifying the intermediate short chain fatty acid stream by distilling the intermediate short chain fatty acid in a second distillation column, forming a free fatty acid; wherein impurities and unmixed whitening compound is removed from the intermediate short chain fatty acid in the residual product stream.

    Abstract: A method of reducing the formation of an impurity in a terephthalic acid (TPA) production process includes: combining in a reactor, a catalyst, a mixture comprising the impurity and the TPA, and a compound comprising an active carbon atom; reacting the impurity with the compound in the presence of the catalyst by a condensation-dehydration reaction process comprising a nucleophilic addition of the active carbon atom of the compound to a carbonyl group of the impurity to form an intermediate followed by a dehydration reaction of the intermediate to form a product mixture comprising a water, the TPA, and an alkene; and recovering the product mixture from the reactor.
