Publication number: 20100222536Abstract: A method for functionalizing the wall of single-wall or multi-wall carbon nanotubes involves the use of acyl peroxides to generate carbon-centered free radicals. The method allows for the chemical attachment of a variety of functional groups to the wall or end cap of carbon nanotubes through covalent carbon bonds without destroying the wall or endcap structure of the nanotube. Carbon-centered radicals generated from acyl peroxides can have terminal functional groups that provide sites for further reaction with other compounds. Organic groups with terminal carboxylic acid functionality can be converted to an acyl chloride and further reacted with an amine to form an amide or with a diamine to form an amide with terminal amine. The reactive functional groups attached to the nanotubes provide improved solvent dispersibility and provide reaction sites for monomers for incorporation in polymer structures. The nanotubes can also be functionalized by generating free radicals from organic sulfoxides.Type: ApplicationFiled: May 12, 2010Publication date: September 2, 2010Applicant: William Marsh Rice UniversityInventors: Valery N.

Publication number: 20080188385Abstract: A polyalkenyl succinic anhydride is prepared with low amounts of resinous or chlorinated byproducts in a two-step process whereby a polyalkene is first reacted with an unsaturated organic acid in a thermal ene reaction, followed with exposure to a gaseous halogen in presence of an additional amount of the unsaturated organic acidic reagent. The foregoing process produces a polyisobutenyl succinic anhydride having a high ratio of succinic anhydride functional groups to polyisobutenyl backbone groups. Such a polyisobutenyl succinic anhydride is particular suitable for the production of oil-soluble hydrocarbyl succinimides that have good dispersant properties when added to lubricating oil compositions.Type: ApplicationFiled: February 1, 2007Publication date: August 7, 2008Inventors: Chente Huang, John T.

Patent number: 7371362Abstract: A process for converting lactose into carbon dioxide and/or carbon monoxide using catalytic wet oxidation. Oxygen gas and an aqueous solution of lactose are fed to a reactor comprising a Pt/Al2O3 catalyst, a Mn/Ce catalyst or a Pt/Mn—Ce catalyst, and the lactose is oxidized in the reactor at elevated temperature and pressure to produce at least one of small organic acids, carbon dioxide, carbon monoxide, water and combinations thereof. The small organic acids may be further degraded by feeding the small organic acids and oxygen gas into a reactor containing a Mn/Ce catalyst and oxidizing the small organic acids to water and at least one of carbon dioxide, carbon monoxide and combinations thereof.Type: GrantFiled: February 21, 2007Date of Patent: May 13, 2008Assignee: Michigan Technological UniversityInventor: Joseph Holles
