Patent number: 10377647Abstract: Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.Type: GrantFiled: December 15, 2011Date of Patent: August 13, 2019Assignees: Queen's University at Kingson, Greencentre CanadaInventors: Philip G.

Publication number: 20160244548Abstract: The present application provides a composite material that comprises a solid and solid-supported non-polymeric switchable moiety, wherein the switchable moiety comprises a functional group that is switchable between a first form and a second form, said first form being neutral and hydrophobic, and said second form being ionized and hydrophilic. The composite material converts to, or is maintained in, said second form when the switchable moiety is exposed to CO2 at amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when CO2 is removed or reduced to an amount insufficient to maintain the ionized form. CO2 is removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N2, Ar, or air. Envisioned uses of these composite materials includes removing water from non-aqueous solvents, removing water vapour from gaseous mixtures, and cleaning industrial reaction vessels and/or pipelines.Type: ApplicationFiled: September 18, 2014Publication date: August 25, 2016Applicants: Queen's University at Kingston, GreenCentre CanadaInventors: Kyle J.
