Bioethanol is used widely as a solvent and is considered a potential liquid fuel. Ethanol can be produced from biomass by fermentation, which results in low concentrations of alcohol in water. Conventional distillation is normally used to separate ethanol from water, but it required high energy consumption. Therefore, alternative approaches to this separation are being pursued. This study examined the potential use of poly(ionic liquid)s (PILs) for the extraction and separation of alcohols from the aqueous phase. Hydrophobic PILs were developed and evaluated by the adsorption of ethanol from ethanol/water solutions. All the necessary parameters, such as cations and anions of the ionic liquid, morphology of the polymer and processing conditions, were evaluated.
生物乙醇被广泛用作溶剂，被认为是一种有潜力的液体燃料。乙醇可以通过发酵从生物质中产生，这会导致水中的酒精浓度较低。传统的蒸馏通常用于将乙醇从水中分离出来，但它需要大量的能源消耗。因此，人们正在寻求替代的分离方法。本研究考察了聚（离子液体）（PILs）在从水相中萃取和分离醇类方面的应用潜力。通过从乙醇/水溶液中吸附乙醇来开发和评估疏水性 PILs。评估了所有必要的参数，如离子液体的阳离子和阴离子、聚合物的形态和加工条件等。
