    Abstract: Processes and compositions reduce free fatty acid (FFA) in oils and fats and in neutral or acidic alkyl ester. The oils and fats or alkyl ester is heated to temperatures from 90 °F to 150 °F, and lower numbered alcohol and dilute caustic are added. The mixture is stirred moderately, and allowed to settle into two phases − a FFA phase and a second low FFA phase, containing either oils and fats or alkyl ester. The two phases are separated. The recovery of both glycerin and lower numbered alcohols is increased. Some compositions for reducing FFA comprise lower numbered alcohol and dilute caustic. The processes and compositions reduce FFA levels to meet fuel standards.

    Abstract: Ketocarboxylic acids such as levulinic acid can be efficiently purified in high yield by esterification with a hydrocarbon polyol to the corresponding polyketocarboxylic ester, which can be readily purified, for example recrystallized. After purification, the ketocarboxylic ester can be hydrolyzed to provide pure ketocarboxylic acid, or a salt thereof, after removal of the esterifying hydrocarbon polyol, or used for other synthetic transformations. Advantageously, the polyketocarboxylic esters, ketocarboxylic acids, and salts thereof produced by this method are obtained in high purity.

    Abstract: The processes disclosed herein for separation of glucaric acid via antisolvent crystallization and azeotropic drying separate monopotassium glucarate and glucaric acid with a recovery yield of greater than 99.9 % and 71 % at purities of about 95.6 % and 98.3 %, respectively. Processes disclosed herein recycle antisolvents such as IPA and acetone with greater than 99 % recovery with an energy consumption of about 20 MJ/kg for isolation of potassium glucarate and 1,456 MJ/kg for glucaric acid. Using methods and processes disclosed herein, other oxygenated bio-carboxylic acids (e.g., mevalonic acid) can be separated and recovered from fermentation broths and abiotic reaction solutions.
