  • Patent number: 9221741
    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.

  • Patent number: 9212176
    Abstract: Disclosed herein is a polyketal adduct obtained by forming an ester between a hydrocarbon polyol and a ketocarboxylic acid to produce an intermediate polyketocarboxylic ester. The intermediate polyketocarboxylic ester can be purified via crystallization to achieve purities of greater than 99.0% and then ketalized to produce the polyketal adduct, which can be used in polymer compositions. The polyketal adduct I is obtained at high purity and at high yield.
