Abstract Experimental and computational study of the interactions between paracetamol and amino acid based ILs; [Ch][Gly], [Ch][L-Ala], and [Ch][L-Val] have been carried out in aqueous media at temperature range (298.150 - 313.150) K. In the experimental section, the density and speed of sound for ternary solutions containing (ILs + H2O + Paracetamol) have measured, and the standard partial molar volume and partial molar isentropic compressibility have evaluated trough Redlich-Mayer equation. Also, the standard apparent molar expansibility has been obtained for ACP in the studied solutions to find out parameters influences the volume, and clearly the temperature and size of anion are dominant factors. So that, the volume of the paracetamol increases with increasing anion size by rising temperature. The Hepler constant has evaluated from temperature derivation of the standard apparent molar expansibility, and is used as describe the structure making or breaking tendency of the paracetamol in the studied solutions. The decrease in the negative values of Δ tr V ϕ 0 , and increase in Δ tr K ϕ 0 values with an increase in the AA-ILs concentration indicates that the nonpolar – nonpolar and polar - nonpolar interactions between the API-IL and amino acid are dominant. The SPT theory was used to compare the standard partial molar volume contribution, which results show that the obtained values are in good agreement with the experimental data. Finally, Gaussian analysis was used to calculate the interaction energies of the systems in the specified structure.

一些可持续氨基酸基离子液体水溶液中扑热息痛的热力学和计算研究

摘要 扑热息痛和基于氨基酸的 ILs 之间相互作用的实验和计算研究;[Ch][Gly]、[Ch][L-Ala] 和 [Ch][L-Val] 已在温度范围 (298.150 - 313.150) K 的水性介质中进行。在实验部分,密度和测量了含有(ILs + H2O + 扑热息痛)的三元溶液的声速,并通过 Redlich-Mayer 方程评估了标准偏摩尔体积和偏摩尔等熵压缩率。此外,已经获得了所研究溶液中 ACP 的标准表观摩尔膨胀率,以找出影响体积的参数,并且显然温度和阴离子大小是主要因素。因此,对乙酰氨基酚的体积随着温度升高而增加阴离子大小而增加。Hepler 常数是根据标准表观摩尔膨胀率的温度推导来评估的,用于描述研究溶液中扑热息痛的结构形成或断裂趋势。Δ tr V ϕ 0 的负值减小,Δ tr K ϕ 0 值随着 AA-ILs 浓度的增加而增加,表明 API-IL 和氨基酸之间存在非极性 - 非极性和极性 - 非极性相互作用占主导地位。利用SPT理论比较了标准偏摩尔体积贡献,结果表明所得值与实验数据吻合较好。最后,利用高斯分析计算特定结构中系统的相互作用能。用于描述研究溶液中扑热息痛的结构形成或破坏趋势。Δ tr V ϕ 0 的负值减小,Δ tr K ϕ 0 值随着 AA-ILs 浓度的增加而增加,表明 API-IL 和氨基酸之间存在非极性 - 非极性和极性 - 非极性相互作用占主导地位。利用SPT理论比较了标准偏摩尔体积贡献,结果表明所得值与实验数据吻合较好。最后,利用高斯分析计算特定结构中系统的相互作用能。用于描述研究溶液中扑热息痛的结构形成或破坏趋势。Δ tr V ϕ 0 的负值减小,Δ tr K ϕ 0 值随着 AA-ILs 浓度的增加而增加,表明 API-IL 和氨基酸之间存在非极性 - 非极性和极性 - 非极性相互作用占主导地位。利用SPT理论比较了标准偏摩尔体积贡献,结果表明所得值与实验数据吻合较好。最后,利用高斯分析计算特定结构中系统的相互作用能。Δ tr K ϕ 0 值随着 AA-ILs 浓度的增加而增加,表明 API-IL 和氨基酸之间的非极性 - 非极性和极性 - 非极性相互作用占主导地位。利用SPT理论比较了标准偏摩尔体积贡献,结果表明所得值与实验数据吻合较好。最后,利用高斯分析计算特定结构中系统的相互作用能。Δ tr K ϕ 0 值随着 AA-ILs 浓度的增加而增加,表明 API-IL 和氨基酸之间的非极性 - 非极性和极性 - 非极性相互作用占主导地位。利用SPT理论比较了标准偏摩尔体积贡献,结果表明所得值与实验数据吻合较好。最后,利用高斯分析计算特定结构中系统的相互作用能。
