Deep eutectic solvents (DES) are one of the most promising green technologies to emerge in recent years given their combination of environmentally friendly credentials and useful functionalities. Considering the continued search for new DES – especially those that exemplify the aforementioned characteristics, we report the preparation of DES based on natural analogues of l‐ascorbic acid for the first time. The onset of eutectic melting occurred at temperatures far below the melting point of the individual components and resulted in the generation of glass forming fluids with glass transition temperatures, viscosities and flow behavior that are comparable to similar systems. This work expands the current array of DES that can be produced using naturally occurring components, which given their potential to be bio‐derived, interesting physicochemical properties (e. g. propensity to supercool and vitrify) and apparent antibacterial nature, may provide utility within a range of applications.

基于天然抗坏血酸类似物和氯化胆碱的低共熔溶剂。

低共熔溶剂 (DES) 兼具环保特性和实用功能，是近年来出现的最有前途的绿色技术之一。考虑到对新 DES 的持续探索，尤其是那些体现上述特征的 DES，我们首次报道了基于L-抗坏血酸天然类似物的 DES 制备。共晶熔化的开始发生在远低于各个组分的熔点的温度下，并导致产生具有与类似系统相当的玻璃化转变温度、粘度和流动行为的玻璃形成流体。这项工作扩展了目前可以使用天然成分生产的 DES 系列，考虑到它们具有生物衍生的潜力、有趣的理化特性（例如过冷和玻璃化的倾向）和明显的抗菌性质，可能会在一系列范围内提供实用性应用程序。
