  • 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.
