Patent number: 5098793Abstract: A large class of crosslinked cyclodextrin resins soluble in water to an extent under about 200 ppm but soluble in an organic solvent to an extent of at least 0.1 weight percent have good film-forming properties with a wide variety of solid phase substrates. The films exhibit excellent adhesive properties toward virtually all solid surfaces which consequently can be readily coated with a thin film having a multiplicity of cyclodextrin moieties available at the surface for seperation and/or purification. Such coated substrates can be prepared in a variety of sizes, shapes, and cyclodextrin loading quite conveniently and relatively inexpensively.Type: GrantFiled: March 23, 1990Date of Patent: March 24, 1992Assignee: UOPInventors: Ronald P.

Patent number: 4958015Abstract: Resins resulting from the crosslinking of cyclodextrin with dicarboxylic acid dihalides often show marginal binding capacity for guest molecules and poor kinetics of guest molecule removal because of the limited porosity of the resins. Resins whose apparent bulk density has been reduced by at least 20% show an enhancement in both of the aforementioned properties resulting from an increase in porosity of the resins. Such resins in general can be formed by conducting the crosslinking reaction in the presence of a blowing agent. The resulting materials retained their desirable physical properties for use in a fixed or packed bed.Type: GrantFiled: September 30, 1988Date of Patent: September 18, 1990Assignee: UOPInventors: Haya Zemel, Mark B. Koch

Patent number: 4902788Abstract: Composites on a porous support of an insolubilized, crosslinked cyclodextrin show improved mass transfer characteristics relative to discrete particles of the same insolubilized cyclodextrin. Dicarboxylic acid dihalides are particularly effective crosslinking agents. The composites can be prepared quite simply and cost effectively by impregnating a support, such as alumina, with a cyclodextrin, then reacting the cyclodextrin within the impregnated support with a suitable dicarboxylic acid dihalide, such as one from the alkane dicarboxylic acid series containing from 4 through 12 carbon atoms.Type: GrantFiled: September 29, 1988Date of Patent: February 20, 1990Assignee: UOPInventors: Haya Zemel, Mark B.
