Abstract: Methods and systems for producing alkyl hydroxyalkanoate from hydroxycarboxylic acid recovery bottoms. The methods generally comprise the steps of obtaining a hydroxycarboxylic acid recovery bottom, adding a mono-alcohol to the hydroxycarboxylic acid recovery bottom to obtain a first mixture, heating the first mixture, optionally in the presence of a catalyst, to form a reaction product, distilling the reaction product, and recovering an alkyl hydroxyalkanoate fraction.

Abstract: Readily water-miscible beta-glucan suspensions and methods of making and using the same. A readily water-miscible beta-glucan suspension includes a beta-glucan and a water-miscible organic fluid that comprises an alcohol, an alpha-hydroxy acid alkyl ester, a polyalkylene glycol alkyl ether, or a combination thereof, wherein the suspension is sufficient such that mixing with water at a shear rate of 40,000 s-1 or more forms a homogeneous mixture of the suspension and the water. The present invention also provides methods of dispersing the water-miscible beta-glucan suspension in water to form homogenous mixtures of the suspension and the water, methods of treating subterranean formations with such homogeneous mixtures, and methods of making the suspension.
