摘要

超声研究可以进一步阐明分子相互作用,从而了解溶质分子和溶剂分子在液体混合物和溶液中的行为。在298 K温度和2 MHz频率下,对不同浓度的1-庚醇在丙烯腈中的声速、密度和粘度进行了测量,以了解分子环境和分子相互作用的程度。二元液体混合物的超声声速研究对于评估组分分子之间的弱、强相互作用和关联具有重要意义。利用超声声速计算了丙烯腈中正庚醇的绝热压缩率(βa)、分子间自由长度(Lf)、声阻抗(Z)和弛豫时间(τ)等声学参数,并预测了浓度对分子相互作用的影响。

ULTRASONIC INVESTIGATION OF MOLECULAR INTERACTIONS IN BINARY LIQUID MIXTURES AT 298 K AND 2 MHZ FREQUENCY
: Ultrasonic studies may throw more light on the molecular interaction to know the behaviour of solute and solvent molecules in liquid mixtures and solutions. Measurements of ultrasonic velocity, density and viscosity have been carried out for 1-Heptanol in Acrylonitrile at different concentrations at 298 K temperature and 2 MHz frequency, to provide information about molecular environment and extent of molecular interaction by ultrasonic technique. Ultrasonic velocity study of binary liquid mixture has gained much importance in assessing the weak and strong molecular interactions and association between the component molecules. Acoustical parameters such as adiabatic compressibility (βa), intermolecular free length (Lf), Acoustic Impedance (Z) and Relaxation time (τ) for n-Heptanol in Acrylonitrile were calculated from ultrasonic velocity and effect of concentration on molecular interaction was predicted.
