  • Metal alloy catalyst composition
    Patent number: 8592340
    Abstract: This invention relates to the composition of metal alloy-doped heterogeneous catalysts and their method of use. In particular the present invention relates to the composition and use of cost-effective metal alloy-doped ion exchange resin catalysts which provide for comparable yield and selectivity compared to the catalysts previously used.
    Type: Grant
    Filed: November 24, 2010
    Date of Patent: November 26, 2013
    Assignee: Rohm and Haas Company
    Inventors: Jose Antonio Trejo, Eric J. Langenmayr

  • Inorganic-containing composites
    Patent number: 5540981
    Abstract: Composites, and a method for preparing composites, are provided. The composites have a plurality of domains of inorganic compounds of from 0.4 to 1000 nanometers on the surfaces of a support material. The domains may contain one or more inorganic compounds, the ratio of which can be controlled by the process.

  • Process for toxic agent removal
    Patent number: 5336329
    Abstract: A process for decontaminating a surface contaminated with a toxic agent in which the surface is contacted with a sorbent selected from the class consisting of a carbonaceous resin which contains a strong base in its pores, a macroreticular ion exchange resin which has a strong base hydroxide functionality and which contains water in its pores or a macronet resin which has been impregnated with a Lewis acid and then removing the toxic agent from the surface thereby decontaminating the surface.

  • High-surface-area compositions
    Patent number: 5137926
    Abstract: Polyaromatic fibers or microbeads which are swollen with solvent and crosslinked while swollen in such a way that the expanded, or macronet, structure of the swollen fiber or microbead is stabilized and retained even after drying exhibit high surface area and significant adsorptive capacity.
