In this present investigation, the thermo-acoustic fundamental parameters such as density (ρ) and speed of sound (U) were measured experimentally for the anisidine isomers (2-methoxy aniline, 3-methoxy aniline and 4-methoxy aniline) with solvent agent such as 2-methyl cyclohexanone in various concentrations within temperatures from 303.15 to 313.15K (5K interval) at ambient atmospheric pressure. From these experimentally determined values, various thermo-acoustic parameters of excess isentropic compressibility, K and excess molar volume, V are calculated. The calculated excess functions were correlated with reduced Redlich-Kister polynomial equation and results are analyzed in terms of structural molecular interactions between component molecules. Moreover, calibration of the partial molar volume's and partial isentropic compressibility’s of components shows strong interaction in 2-methyl cyclohexanone + 4-methoxy aniline than any other composites. In addition to the FTIR characteristic spectrum of all combinations at different concentrations gives the more promising features such as interaction behavior that helps our analysis to guide the interactions of individual bonding strength of the molecules.

根据不同温度下的热声参数，研究了2-甲基环己酮与邻茴香胺/间茴香胺/对茴香胺的二元液体混合物的分子间相互作用

在本研究中，使用溶剂剂通过实验测量了茴香胺异构体（2-甲氧基苯胺，3-甲氧基苯胺和4-甲氧基苯胺）的热声基本参数，例如密度（ρ）和声速（U）。例如在环境大气压下，温度在303.15至313.15 K（间隔5 K）内的各种浓度的2-甲基环己酮。根据这些实验确定的值，可以计算出等熵压缩率K和过量摩尔体积V的各种热声参数。计算出的多余函数与减少的Redlich-Kister相关根据组成分子之间的结构分子相互作用来分析多项式方程式和结果。而且，组分的部分摩尔体积和部分等熵可压缩性的校准显示，在2-甲基环己酮+ 4-甲氧基苯胺中的相互作用强于任何其他复合材料。除了FTIR以外，所有组合在不同浓度下的特征光谱还提供了更有前途的功能，例如相互作用行为，这有助于我们的分析来指导分子各个键强度的相互作用。
