Abstract:Ionic liquids (ILs) have been utilized in a variety of applications owing to their nonflammability, low volatility, and tunable chemical properties. However, removing impurities during the synthesis process is complex and costly. In this work, we introduce a novel and cost-effective method to purify [bmim][BF 4 ], an IL, by inducing phase separation using a halocarbon refrigerant such as chlorodifluoromethane . The technique utilizes a ternary phase diagram consisting of [bmim][BF 4 ], water, and halocarbons t… Show more
