摘要

The ultrasonic velocity (u) and density (q) of binary mixtures of 2-Chloroethanol (2-CletOH) with 2- Dimethylaminoethanol (DMAE) and 2-Diethylaminoethanol (DEAE) have been measured over the entire concentration range at temperatures 293.15, 303.15 and 313.15 K. The ultrasonic velocity and density data are used to estimate adiabatic compressibility (bs), intermolecular free length (Lf), molar sound velocity (R), molar compressibility (B) and specific acoustic impedance (Z) along with excess values of ultrasonic velocity (uE), adiabatic compressibility (bf), intermolecular free length (Lf), acoustic impedance (ZE) and molar volume (Vjj,). The infrared spectra of both of the systems, 2-CletOH + DMAE and 2-Clet- OH + DEAE, have also been recorded at room temperature (298.15 K). The observed variations of these parameters, with concentration and temperature, are discussed in terms of the intermolecular interactions between the unlike molecules of the binary mixtures.
