Although petroleum is widely used to make solvents and to produce energy, solvents derived from it, such as acetonitrile, may not be the safest and most sustainable options currently available. Additionally, processes such as the Fischer–Tropsch synthesis emerge as an intelligent alternative to produce energy from coal, biomass, or natural gas to supply the increasing demand for petroleum-derived products. Thus, with a green solvent, γ-valerolactone, applied to the removal of oxygenated compounds from a Fischer–Tropsch process stream, this work suggests the application of a less toxic solvent to an alternative energy production process through model systems. In this sense, liquid–liquid equilibrium experimental data were measured for systems composed of an oxygenated solute (1-heptanol, propanone, 2-butanone, or 2-heptanone) + γ-valerolactone + n-tetradecane at 298.15 K. The liquid–liquid equilibrium data were successfully correlated by the nonrandom two-liquid model with a medium average deviation lower than 1%. Therefore, the measured experimental data may contribute to the design of a liquid–liquid extraction process applied to the refinement of synthetic crude oil from a Fischer–Tropsch synthesis.

三元混合物的液-液平衡（1-庚醇，丙酮，2-丁酮或2-庚酮+γ-戊内酯+ n-十四烷基）

尽管石油被广泛用于制造溶剂和产生能量，但由石油衍生的溶剂（例如乙腈）可能不是当前可用的最安全，最可持续的选择。此外，诸如费-托合成的过程作为从煤炭，生物质或天然气中产生能量的智能替代品应运而生，从而满足了对石油衍生产品日益增长的需求。因此，将绿色溶剂γ-戊内酯应用于费-托工艺流中的含氧化合物的去除，这项工作表明通过模型系统将毒性较小的溶剂应用于替代能源生产过程中。从这个意义上讲，测量了由氧化溶质（1-庚醇，丙酮，2-丁酮或2-庚酮）+γ-戊内酯+组成的系统的液-液平衡实验数据。正十八烷在298.15K。液-液平衡数据已通过非随机两液模型成功关联，中等平均偏差低于1％。因此，测得的实验数据可能有助于液-液萃取工艺的设计，该工艺适用于从费-托合成法提炼合成原油。
