多组分吸收测量在实验和分析上都是非常困难的,这就是为什么文献缺乏信息的原因,即使结果对于理解真实的分离系统很重要。在使用离子液体(IL)设计氢氟碳化合物(HFC)制冷剂混合物的分离工艺时,了解多组分效应非常重要;然而,几乎所有已发表的结果都针对单组分HFC/IL系统。为了应对这一挑战,Hiden Isochema设计了利用积分质量平衡(IMB)方法的新型重量微量天平,以有效且准确地测量具有低挥发性的液体(例如,IL)和固体。本文研究了298.15 K下二氟甲烷(HFC-32)和五氟乙烷(HFC-125)在两种离子液体(1-正丁基-3-甲基咪唑四氟硼酸盐和1-正丁基-3-甲基咪唑六氟磷酸盐)中的混合吸收,以了解HFC混合物/离子液体的相互作用。这些最先进的仪器首次允许测量离子液体中的HFC二元气体混合物,可以与现有的单一气体溶解度测量进行比较。
Multicomponent absorption measurements are notoriously difficult both experimentally and analytically, which is why the literature is lacking information, even though the results are important for understanding real separation systems. In the case of designing a separation process for hydrofluorocarbon (HFC) refrigerant mixtures using an ionic liquid (IL), it is important to understand multicomponent effects; however, almost all published results are for single component HFC/IL systems. To address this challenge, new gravimetric microbalances utilizing the Integral Mass Balance (IMB) method have been designed by Hiden Isochema to efficiently and accurately measure multicomponent gas sorption in liquids with low volatility (e.g., ILs) and solids. The present work investigates the mixture absorption of difluoromethane (HFC-32) and pentafluoroethane (HFC-125) in two ILs (1-n-butyl-3-methylimidazolium tetrafluoroborate and 1-n-butyl-3-methylimidazolium hexafluorophosphate) at 298.15 K for the purpose of understanding HFC mixture/IL interactions. For the first time, these state-of-the-art instruments have allowed for the measurement of an HFC binary gas mixture in ILs that can be compared with existing single gas solubility measurements.
