Abstract: Methods and systems for producing alkyl hydroxyalkanoates 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: Compositions including ester-form sophorolipids and acidic-form sophorolipids having from 10 to 70 percent by weight of a pour point depressant, from 4 to 50 percent by weight total solids, and from 10 to 40 percent by weight water are disclosed. In some embodiments, the compositions exhibit a pour point of less than 300 F, a flowback number of at least 60 and a pH of at least 5.

Abstract: A process to produce a sophorolipid composition is disclosed, the steps including obtaining a sophorolipid containing composition having a pH of less than 5, adding 6 percent by weight or less of a free fatty acid to the composition, and thereafter adjusting the pH of the composition to a pH greater than 5. In some embodiments, the sophorolipid composition initially comprises from 4 to 80 percent by weight dry solids.

Abstract: In some embodiments a permanent cache list of files not to be removed from a cache is determined in response to a user selection of an application to be added to the cache. The determination is made by adding a file to the cache list if the file is a static dependency of the application, or if a file has a high probability of being used in the future by the application. Other embodiments are described and claimed.

Abstract: A method for loading files for a hardware device. An operating system requests from a user a location of a first file component for the hardware device. The operating system receives input from the user that provides the location. A file at the location loads the first file component from the location and indicates to the operating system that the location contains a second file component for the hardware device. The operating system retrieves from the location the second file component for the hardware device.

Abstract: In a first step of the method, the gas mixture to be treated is injected into a column swept by a continuous stream of carrier gas and containing a suitable selective solid adsorbent until saturation of this latter by the adsorbed constituent of the gas mixture. In a second step, small quantities of the mixture to be treated and representing a fraction of the quantity injected into the column during the first step are injected periodically so as to collect successively at the column outlet a fraction which is enriched in the non-adsorbed constituent and a fraction which is purified in the adsorbed constituent.
