  Design, synthesis, and solution behaviour of small polyamines as switchable water additives

  摘要：

  工业上通常避免在水中加盐，以促使污染物盐化或打破乳状液和悬浮液，因为事后对盐水进行必要处理的费用很高。然而，使用可转换水这种离子强度可转换的水溶剂，可以通过引入和去除二氧化碳，在水溶液中可逆地生成和消除盐分。为了提高这些可转换盐的效率，我们对它们的反应性和溶液行为进行了物理建模研究，为未来的可转换水添加剂制定了一套设计原则。利用该模板合成的多胺显示出了可转换水添加剂的最高效率。

  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.

  本文介绍了使用可切换水的方法和系统，这种水能够在初始离子强度和增加的离子强度之间可逆切换。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、脱盐、粘土沉淀、粘度切换等。使用低能耗方法，如用 C02、CS2 或 COS 鼓泡，或用勃朗斯特酸处理，很容易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、惰性气体鼓泡、加热、搅拌、抽真空或部分抽真空，或以上方法的任意组合。

  The practice of adding salt to water to induce salting out of contaminants or to break emulsions and suspensions is generally avoided industrially because of the expense of the necessary treatment of the salty water afterwards. However, the use of switchable water, an aqueous solvent with switchable ionic strength, allows for reversible generation and elimination of salts in aqueous solution, through the introduction and removal of CO2. In the effort to improve the efficiency of these switchable salts, a physical study modeling their reactivity and solution behaviour has been performed, resulting in a set of design principles for future switchable water additives. The resulting polyamines synthesized using this template show the highest efficiency recorded for a switchable water additive.
