In terms of solute–solute and solute–solvent interactions, thermodynamic properties help characterize the structure and behavior of solutions. To identify the solute–solvent interactions, experimental density and speed of sound data at (288.15 K–318.15 K) at a 10 K interval have been measured for the aqueous mixtures of branched-chain acetyl substituted l-glycine and l-leucine with ILs. The measured data have been used to determine the apparent molar volume (V_ϕ), the partial molar volume, and standard partial molar volumes of transfer, molar isentropic compression, and partial molar isentropic compression of transfer. Also, both these properties have calculated pair and triplet interaction coefficients. Understanding mixing effects and other complex biological processes will be aided by the thermodynamic parameters discovered from the hydrophilic head of the amino acids and the alkyl group of the long-chain ILs.

支链氨基酸在不同温度下 1-十二烷基-3-甲基咪唑溴化物水溶液中的溶剂化性质：体积和声学测量

就溶质-溶质和溶质-溶剂相互作用而言，热力学性质有助于表征溶液的结构和行为。为了确定溶质-溶剂相互作用，在（288.15 K-318.15 K）处测量了以 10 K 间隔测量支链乙酰基取代的l-甘氨酸和l-亮氨酸与 ILs的水性混合物的实验密度和声速数据. 测量数据已用于确定表观摩尔体积 ( V _φ)、偏摩尔体积、转移的标准偏摩尔体积、摩尔等熵压缩和转移的偏摩尔等熵压缩。此外，这两个属性都计算了对和三重态交互系数。从氨基酸的亲水头部和长链 IL 的烷基中发现的热力学参数将有助于理解混合效应和其他复杂的生物过程。
