  • Patent number: 8722956
    Abstract: Methods and kits for decomposing organophosphorus compounds in non-aqueous media at ambient conditions are described. Insecticides, pesticides, and chemical warfare agents can be quickly decomposed to non-toxic products. The method comprises combining the organophosphorus compound with a non-aqueous solution, preferably an alcohol, comprising metal ions and at least a trace amount of alkoxide ions. In a first preferred embodiment, the metal ion is a lanthanum ion. In a second preferred embodiment, the metal ion is a transition metal.
    Type: Grant
    Filed: January 24, 2011
    Date of Patent: May 13, 2014
    Assignee: Queen's University at Kingston

  • Publication number: 20100202950
    Abstract: Efficient heterogeneous catalysts were prepared by derivatization and palladation of commercially available chloromethylated polystyrene, and derivatization and palladation of functionalized silica gels with benzylchloride pendant groups. Both polymer based and silica based heterogeneous catalysts exhibited catalytic activity. Catalytic activity was studied using methanolysis of commercially available P?S pesticides. Catalytic activity of catalysts immobilized on silica gel was greater than catalyst immobilized on polymer.
