从这个角度来看，从溶剂到溶剂的个人旅程展示了环境友好型溶剂如何成为各种化学挑战解决方案的一部分。溶剂是自然界的重要组成部分，为化学反应和过程提供一个或多个液相。虽然有些溶剂可以从大自然中大量获得，但大多数溶剂都是人造的。历史上，溶剂的开发和/或选择仅有助于用户的化学或物理目标。随着地方和全球健康和环境问题日益重要，包括采用绿色化学和分子方法预防污染，溶剂的潜在影响成为重要的选择工具。绿色化学的关键原则之一是消除化学过程中的溶剂或用环境友好的溶剂代替有害溶剂。开发无溶剂替代工艺是最佳解决方案，特别是当底物或产物之一为液体并可用作反应溶剂时。但是，如果溶剂对工艺至关重要，我们应该选择对健康和环境没有影响或影响有限的溶剂。
In this perspective, a personal journey from solvent to solvent is presented to demonstrate how environmentally friendly solvents can be part of the solution of various chemical challenges. Solvents are important components of Nature to provide one or more liquid phases for chemical reactions and processes. While some solvents are available from Nature even in large quantities, most of the solvents are man-made. Historically, solvents were developed and/or selected to help the chemical or physical objectives of the user(s) only. With the increasing importance of local and global health and environmental issues, including the introduction of green chemistry and the molecular approach for pollution prevention, the potential impacts of solvents became important selection tools. One of the key principles of green chemistry is the elimination of solvents in chemical processes or the replacement of hazardous solvents with environmentally benign solvents. The development of solvent-free alternative processes is the best solution, especially when either one of the substrates or the product is a liquid and can be used as the solvent of the reaction. However, if solvents are crucial to a process we should select from solvents that will have no or limited impact on health and the environment.
