  • Patent number: 11400331
    Abstract: A method of detoxifying a liquid chemical agent is provided using a surface-modified metal organic framework having an amine-based compound deposited on a surface and pores thereof, or bonded to the inside of a frame, wherein when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs and, the liquid chemical agent is removed through a hydrolysis reaction, thereby detoxifying chemical agents, such as nerve agents and vesicants, and assuring a high detoxification effect on liquid chemical agents at room temperature even with a small amount of the surface-modified metal organic framework.

  • Patent number: 11383220
    Abstract: The method and materials of this invention make possible substantially faster techniques for organic-aqueous extractions and routine chemical reactions work-ups. The inventive material uses silicone elastomer-coated glass powders, magnetic powders, and sponges as absorbents to extract organic products from an aqueous mixture. After separation from the mixture, these different forms now loaded with organic products can serve as a convenient input for flash chromatographic separations or other processing. With these techniques, tedious liquid-liquid extractions are replaced by a simple solid filtration or transfer and emulsion formation is eliminated. These versatile sorbents can also be used for larger scale work-ups, various extractions of organics from an aqueous solution (e.g., water purification) or gas phase and various analytical or other applications.
