In the current work, Density and speed of sound (ultrasonic speed) of liquid mixtures of (ethylene, diethylene and triethylene glycols + aqueous glutaraldehyde solutions) have been investigated at the temperature ranges of (293.15 K, 298.15 K, 303.15 K and 308.15 K) and in the concentration of (0.01, 0.02, 0.03 and 0.04) mol·kg⁻¹. Different thermodynamic and acoustic parameters have also been calculated using density and speed of sound experimental values. V_ϕ (apparent molar) and V_ϕ⁰ (partial molar) volumes and ΔV_ϕ⁰ (partial molar volume of transfer) have been estimated using experimental values of density. Using speed of sound values, K_{ϕ, s} (apparent molar) and K_{ϕ, s}⁰ (partial molar) isentropic compressions and ΔK_{ϕ, s}⁰ (partial molar isentropic compression of transfer) have been obtained. Using partial molar volume of transfer and partial molar isentropic compression of transfer values, the pair and triplet interaction coefficients have also been computed. The final outcome of the research is studied in terms of solute-solvent interactions between the molecules of liquid mixtures.

在当前的工作中，已经研究了在（293.15 K，298.15 K，303.15 K和308.15 K）温度范围内（乙烯，二甘醇和三甘醇+戊二醛水溶液）的液体混合物的密度和声速（超声波速度） ）和（0.01、0.02、0.03和0.04）mol·kg ^-1的浓度。还使用声音实验值的密度和速度来计算不同的热力学和声学参数。使用密度的实验值估算了V _ϕ（表观摩尔）和V _ϕ ⁰（部分摩尔）体积以及ΔV _ϕ ⁰（转移的部分摩尔体积）。使用正确的价值观的速度，ķ _φ，s（表观摩尔）和K _ϕ，s ⁰（部分摩尔）等熵压缩和ΔK _ϕ，s ⁰（转移的等摩尔等熵压缩）。使用转移的部分摩尔体积和转移值的部分摩尔等熵压缩，还计算了对和三重态相互作用系数。研究的最终结果是根据液体混合物分子之间的溶质-溶剂相互作用进行研究的。
