  • Polysaccharide modification in densified fluid
    Patent number: 5977348
    Abstract: This invention relates to a process for chemically modifying polysaccharides in a densified fluid. In particular, the modification includes esterification and/or etherification of a starch in supercritical carbon dioxide. The process is advantageous in that it allows for a high degree of substitution without the use of organic solvents or repeated reactions.

  • Dry cleaning system using densified carbon dioxide and a surfactant adjunct
    Patent number: 5683977
    Abstract: A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO.sub.2. The surfactant has a polysiloxane, a branched polyalkylene oxide and a halocarbon group which is a functional CO.sub.2 -philic moiety connected to a CO.sub.2 -phobic functional moiety. The surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
    Type: Grant
    Filed: March 6, 1995
    Date of Patent: November 4, 1997
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Sharon Harriott Jureller, Judith Lynne Kerschner, Myongsuk Bae-Lee, Lisa Del Pizzo, Rosemarie Harris, Carol Resch, Cathy Wada
  • Method of dry cleaning fabrics using densified liquid carbon dioxide
    Patent number: 5683473
    Abstract: A method of dry cleaning fabrics using a dry cleaning system is described. The system comprises densified carbon dioxide, preferably in a liquid phase, and a selected surfactant which is soluble in the densified CO.sub.2. The surfactant has a polysiloxane, a branched polyalkylene oxide or a halocarbon group which is a functional CO.sub.2 -philic moiety connected to a CO.sub.2 -phobic functional moiety. The surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
    Type: Grant
