Definitions

  • the present invention provides a water insoluble polymeric composition
  • a water insoluble polymeric composition comprising a reaction product of a cyclodextrin monomer and a polyfunctional crosslinker selected from the group consisting of polyisocyanates, dihalohydrocarbons, and dihaloacetylhydrocarbons.
  • the present invention further provides a process for removing a target organic compound from an aqueous composition
  • a process for removing a target organic compound from an aqueous composition comprising contacting said aqueous composition containing a target organic compound with a water insoluble cyclodextrin polymer comprising a reaction product of a cyclodextrin monomer and a polyfunctional crosslinker selected from the group consisting of polyisocyanates, dihalohydrocarbons, and dihaloacetylhydrocarbons for time sufficient to form a reaction product between said water insoluble cyclodextrin polymer and said target organic compound whereby the concentration of said target organic compound in said aqueous composition is reduced.
  • FIGURE 1 is a graph showing induced circular dichroism of a cyclodextrin polymer complex with para-nitrophenol.
  • FIGURE 2 is a graph showing a second harmonic generation signal versus incident angle.
  • water insoluble is a relative term and as used herein generally refers to materials having a solubility in water of no greater than about 0.01 grams per gram of water.
  • the cyclodextrin polymers of this invention can have a nanoporous structure capable of absorbing selected target organic compounds from within aqueous streams, solutions or compositions down to levels as low as parts per billion (ppb) and even to levels of parts per trillion (ppt).
  • Diisocyanates can include such as 2,6-tolylene diisocyanate, 2,4-tolylene diisocyanate (TDI), 4,4'-diphenylmethane diisocyanate (MDI), hexamethylene diisocyanate (HDI), and the like.
  • Dihalohydrocarbons can be generally represented by the formula X-R'-X where
  • suitable dihalohydrocarbons may include 1,3-dichloropropane, 1,3-dibromopropane, 1,3-diiodopropane, 1,6- dichlorohexane, 1 ,6-dibromohexane, 1 ,6-diiodohexane, 1,8-dichlorooctane, 1,8- dibromooctane, 1,8-diiodooctane, 1 ,4-chloromethylenebenzene, 1,4- bromomethylenebenzene, and 1 ,4-iodomethylenebenzene.

  • Optical quality thin films can be prepared from the water insoluble cyclodextrin polymers of the present invention. Such thin films can then absorb organic chromophores from water. Some chromophores can be nonlinear optical materials, typically for polar molecules.
  • EXAMPLE 2 To 2.0 g of dried ⁇ -cyclodextrin ( ⁇ -CD) in 10 ml of dried DMF, 1 ,6-diisocyanatohexane (HDI) was added dropwise with vigorous stirring. The total volume of HDI added was 2.5 ml. Under a nitrogen atmosphere, the solution was heated at 80°C for 16 hours. A polymeric material was then recovered from the solution as a clear, transparent solid. Residual DMF was removed by heating under vacuum at 80°C for 24 hours. As in example 1, the resultant product was a polymeric cyclodextrin solid which could easily be ground into a powder.
  • HDI 1,6-diisocyanatohexane
  • TDI toluene 2,4-diisocyanate
