In the present study, intermolecular interactions for binary liquid mixtures of 1-propoxy-2-propanol with amines namely diisopropylamine, dibutylamine and tributylamine have been examined through experimentally measured values of density (\(\rho\)), speed of sound (u) and viscosity (\(\eta\)). Measurements were carried out over entire the composition range and temperature range from 298.15 to 308.15 K. Various excess and deviation parameters have been calculated using measured data. These excess and deviation properties have been discussed in terms of intermolecular interactions in the mixtures. The presence of strong intermolecular interactions among unlike molecules in binary mixtures of 1-propoxy-2-propanol with diisopropylamine and dibutylamine while weak interactions in case of tributylamine have been revealed by these properties. Excess and deviation properties have been correlated with composition using Redlich–Kister polynomial. The Jouyban–Acree model was used to correlate the measured data with composition. Further, studies on Fourier-transform infrared spectroscopy were also carried out at room temperature.

在本研究中，1-丙氧基-2-丙醇与胺（即二异丙胺、二丁胺和三丁胺）的二元液体混合物的分子间相互作用已通过实验测量的密度值 (\(\rho))、声速( u ) 和粘度 ( \(\eta\)). 在 298.15 至 308.15 K 的整个组成范围和温度范围内进行了测量。使用测量数据计算了各种过量和偏差参数。这些过量和偏差特性已根据混合物中的分子间相互作用进行了讨论。这些特性揭示了 1-propoxy-2-propanol 与二异丙胺和二丁胺的二元混合物中不同分子之间存在强烈的分子间相互作用，而在三丁胺的情况下存在弱相互作用。使用 Redlich–Kister 多项式将过量和偏差特性与成分相关联。Jouyban-Acree 模型用于将测量数据与成分相关联。此外，傅里叶变换红外光谱的研究也在室温下进行。
