摘要

传统空调从富含水分的空气中抽取水分的效率很低，尤其是在炎热潮湿的地区，因为这会导致更高的能耗。液体干燥剂空调（LDAC）系统是一种很有前途的替代方案，因为它能有效控制温度和湿度，具有节能潜力。离子液体（ILs）被认为是传统卤化盐的干燥剂替代品，具有更好的性能且不会腐蚀金属。本研究介绍了以 1,4-二氮杂双环[2.2.2]辛烷 (DABCO) 为阳离子、以三烷基磷酸酯为阴离子的新型离子液体的合成和结构表征。通过电化学测试研究了铜和铝在这些离子液体溶液中的腐蚀行为。最终得到的离子液体具有很强的吸湿性和抗菌性，同时腐蚀性更低，没有结晶风险。这些优点使 DABCO 衍生的离子液体成为下一代潜在的液体干燥剂。

Novel DABCO-Derived Ionic Liquids for Liquid Desiccant Air Conditioning

Conventional air conditioners are inefficient, especially in hot and humid areas, to take water away from the moisture-rich air since this causes higher energy consumption. Liquid desiccant air-conditioning (LDAC) systems represent a promising alternative due to their effective temperature- and humidity-independent control with energy-saving potential. Ionic liquids (ILs) are considered desiccant substitutes for traditional halide salts with better performance and no metal corrosion. This study introduced the synthesis and structure characterization of novel ILs with cations based on 1,4-diazabicyclo[2.2.2]octane (DABCO) and anions derived from trialkylphosphate. The corrosion behavior of copper and aluminum in these IL solutions was studied with an electrochemical test. The resulting ionic liquids were strongly hygroscopic and antimicrobial while showing much lower corrosivity with no risk of crystallization. These advantages made DABCO-derived ILs the potential liquid desiccants of the next generation.
