  • CONVERSION METHOD
    Publication number: 20090198046
    Abstract: A process for the preparation of water-soluble cellulose hydrolysis products, which comprises admixing cellulose with an ionic liquid in which the cellulose has at least some sollubility, said ionic liquid state at a temperature at or below 150 -C, and treating the resulting solution with an acid in the presence of water, said acid having a pKa in water of less than 2 at 25 -C.

    Inventors: Markus Fanselow, John Holbrey, Kenneth Richard Seddon
  • Ionic liquid reconstituted cellulose composites as solid support matrices
    Publication number: 20070006774
    Abstract: Disclosed are composites comprising regenerated cellulose, a first active substance, a second active substance, and a linker. Methods for preparing the composites that involve the use of ionic liquids are also disclosed. Articles prepared from the disclosed composites and further disclosed.

    Publication date: December 29, 2005
    Applicant: UNIVERSITY OF ALABAMA
    Inventors: John Holbrey, Richard Swatloski, Ji Chen, Dan Daly, Robin Rogers
  • Ionic liquids containing secondary hydroxyl-groups and a method for their preparation
    Publication number: 20050065020
    Abstract: The invention provides ionic liquids having a secondary hydroxyl group, and an atom-efficient method for the preparation of these ionic liquids, by epoxidation of a protonated nitrogen-containing organic base (which can optionally be prepared in situ) in the presence of an anion suitable for supporting ionic liquid formation.
