在这项工作中，一些离子液体（[C8 mim][BF 4]，[C8 mim][NTf 2]和[C2mim][EtSO 4]），这已被证明是合适的燃料油脱硫的萃取溶剂，进行了同步脱氮的能力进行了测试。为此，这些离子液体与吡啶和正己烷的液-液平衡已被确定在298.15 K和大气压下。为了给萃取装置的设计提供有用的参数，采用非随机双液（NRTL）方程对汽、柴油脱硫中涉及的5个三元体系进行了同时关联。当非随机性参数α = 0.3时，得到的结果最好。
In this work, the ability of some ionic liquids ([C8mim][BF4], [C8mim][NTf2], and [C2mim][EtSO4]), which have shown to be suitable as extraction solvents for the desulfurization of fuel oils, has been tested to carry out simultaneous denitrogenation. For this purpose, the liquid−liquid equilibria of these ionic liquids with pyridine and n-hexane have been determined at 298.15 K and atmospheric pressure. With the idea of giving useful parameters for the design of extraction units, the simultaneous correlation of five ternary systems involved in the gasoline and diesel desulfurization was carried out with the nonrandom two-liquid (NRTL) equation. The best results were achieved for a value of the nonrandomness parameter α = 0.3.
