  A solvent that reversibly converts from a hydrophobic liquid form to hydrophilic liquid form upon contact with water and a selected trigger, e.g., contact with CO2, is described. The hydrophilic liquid form is readily converted back to the hydrophobic liquid form and water. The hydrophobic liquid is an amidine or amine. The hydrophilic liquid form comprises an amidinium salt or an ammonium salt.

  描述了一种溶剂，当与水和选择的触发器（例如与CO2接触）接触时，可从疏水液态形式可逆地转变为亲水液态形式。亲水液态形式很容易转变回疏水液态形式和水。疏水液态是一种酰胺或胺。亲水液态形式包括酰胺盐或铵盐。

• WATER WITH SWITCHABLE IONIC STRENGTH

  公开（公告）日：2020-05-20

  A method and system for reversibly converting water between an initial ionic strength and an increased ionic strength, using a switchable additive, is described. The disclosed method and system can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions. Following extraction of a solute from a medium by dissolving it in water, the solute can then be isolated from the aqueous solution or "salted-out" by converting the water to a solution having an increased ionic strength. The solute then separates from the increased ionic strength solution as a separate phase. Once the solute is, for example, decanted off, the increased ionic strength aqueous solution can be converted back to water having its original ionic strength and reused. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with CO2, CS2 or COS. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.

  本文描述了一种利用可切换添加剂在初始离子强度和增加离子强度之间可逆转换水的方法和系统。所公开的方法和系统可用于免蒸馏去除溶剂、溶质或溶液中的水分。将溶质溶于水从介质中提取出来后，可通过将水转化为离子强度增加的溶液，将溶质从水溶液中分离或 "盐析 "出来。然后，溶质作为一个独立的相从离子强度增加的溶液中分离出来。例如，一旦溶质被倾析掉，离子强度增加的水溶液就可以转换回具有原始离子强度的水并重新使用。使用低能耗方法，如二氧化碳、CS2 或 COS 鼓泡，可以很容易地实现从较低离子强度到较高离子强度的转换。从较高的离子强度转换到较低的离子强度可通过低能耗的方法轻松实现，如用空气鼓泡、加热、搅拌、抽真空或部分抽真空，或它们的任意组合。

  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.
