Abstract

The pseudoternary systems of deep eutectic solvents (DESs) has attracted interest in separation technology due to its novel physicochemical properties. Two DESs of [ChCl][DEG] with molar ratios of 1:4 (DES1) and 1:8 (DES2) were prepared. The pseudoternary systems of n-hexane + benzene + DES1 and n-hexane + benzene + DES2 measured the tie lines of liquid–liquid equilibrium (LLE) data at T = 298.15–318.15 K and at atmospheric pressure. The assumption of DESs as the pseudopure component was performed to investigate pseudoternary LLE, which implies that the DESs remain unaltered in a single phase. DES2 was found to substantially increase the selectivity (S) values for the separation of benzene and n-hexane. The Othmer–Tobias and Bachman correlations were used to evaluate the reliability of the experimental tie-line data. The NRTL model shows a good agreement of the calculated and experimental values of n-hexane + benzene + DES1 with the root-mean-square deviation of 0.0076. The pseudoternary system of n-hexane + benzene + DES2 shows a good agreement with the UNIQUAC model with the RMSD of 0.0095. To verify the tie-line consistency, GM/RT was used to topologically analyze the Gibbs mixing energy.

用准三元液-液平衡数据评价二乙二醇基深度共晶溶剂分离苯和正己烷
深共晶溶剂(DESs)伪三元体系以其新颖的物理化学性质引起了分离技术的广泛关注。制备了两种摩尔比分别为1:4 (DES1)和1:8 (DES2)的[ChCl][DEG] DESs。正己烷+苯+ DES1和正己烷+苯+ DES2的赝三元体系在T = 298.15 ~ 318.15 K和常压下测量了液液平衡(LLE)数据的联系线。假设DESs为伪纯组分来研究伪三元LLE,这意味着DESs在单相中保持不变。DES2可显著提高苯和正己烷分离的选择性S值。使用other - tobias和Bachman相关来评价实验系线数据的可靠性。NRTL模型计算值与实验值吻合较好,正己烷+苯+ DES1的均方根偏差为0.0076。正己烷+苯+ DES2的伪三元体系与UNIQUAC模型吻合较好,RMSD为0.0095。为了验证系线的一致性,采用GM/RT对吉布斯混合能进行了拓扑分析。

期刊介绍: The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
