  • Coagulation of chitin from ionic liquid solutions using kosmotropic salts
    Patent number: 10927191
    Abstract: Methods for separating chitin from a chitinous biomass are described, the methods comprising contacting the chitinous biomass with an ionic liquid to form a mixture comprising chitin; contacting the mixture with an aqueous solution of a kosmotropic salt, thereby coagulating the chitin and forming an biphasic system comprising an ionic liquid-chitin phase and an aqueous kosmotropic salt phase; separating the ionic liquid-chitin phase from the aqueous kosmotropic salt phase; and collecting the chitin from the separated ionic liquid-chitin phase, thereby forming a recycled ionic liquid.
    Type: Grant
    Filed: January 5, 2018
    Date of Patent: February 23, 2021
    Assignees: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ALABAMA, 525 Solutions, Inc.
