  • Modified wood with surface coatings
    Patent number: 6602605
    Abstract: A method and process for treating wood. The steps include preparing isocyanate-based reactive prepolymer resins for impregnation, impregnating wood with these impregnation resins, curing the impregnated wood at elevated temperatures, preparing isocyanate resin-based coating materials and applying these coating materials on the cured impregnated wood and curing the coatings at room or elevated temperatures. The resulting treated wood has substantially improved de-contaminability of the chemical warfare agent VX both initially and after long exposure to degradation effects from sunlight.

  • Selective C-alkylation of aniline in the presence of zeolite catalysts to para-aniline
    Patent number: 5081302
    Abstract: The selective ring-alkylation of anilines comprising providing a mixture of a lower alkanol and an aniline, exposing said mixture to a temperature of from 300.degree. C. to 500.degree. C., preferably from 350.degree. C. to 450.degree. C., in the presence of an acidic Y-type zeolite is described. The Y-type zeolites are predominantly selective to the formation of para-alkylanilines.
    Type: Grant
    Filed: April 27, 1989
    Date of Patent: January 14, 1992
    Assignee: First Chemical Corporation
    Inventors: Arthur C. Bayer, Charles U. Pittman, Jr., Lichang Wang, Earl G. Alley, Anthony C. Maliyackel
  • Selective N-alkylation of aniline in the presence of zeolite catalysts
    Patent number: 5030759
    Abstract: The selective N-alkylation of anilines comprising providing a mixture of a lower alkanol and an aniline, exposing said mixture to a temperature of from 250.degree. C. to 350.degree. C. in the presence of an acidic zeolite having a pore size of from 6 to 8 angstroms with a three-dimensional tubular shape, such as S-115 zeolite, is described. These zeolites are predominantly selective to the formation of N-alkylanilines.
