Abstract The interlinkage of ethylene glycol, diethylene glycol and triethylene glycol with d-mannitol at different values of temperature has been analysed by the combination of volumetric and acoustic process. Different values of speed of sound and the density of EG, DEG and TEG in the molalities of (0.01, 0.03 and 0.05) mol kg−1 in aqueous solutions of d-mannitol at T = (293.15, 298.15, 303.15 and 308.15) K have been considered. From the values of speed of sound, the partial molar isentropic compression (Kϕ,s) and the partial molar isentropic compression of transfer (ΔK0𝜙,s ), have been determined. The pair and triplet interaction coefficient have also been estimated. From the density data, the apparent molar volume (V𝜙0 ) and standard partial molar volume of transfer (ΔV𝜙0 ) for EG, DEG and TEG in aqueous d-mannitol solutions have been examined. Using the values of partial molar volume and partial molar isentropic compression of transfer, the pair and triplet coefficients are determined. These noteworthy parameters are helpful to examine the interactions between sugar alcohol + glycols + water solutions.

velocity, viscosity, etc. With these properties, we can ascertain the prominent properties on macroscopic scale. The investigation of corresponding mixtures concerning molar properties plays a crucial role for plotting various industrial progressions (Aryanci and Salim 2008; Kaur and Juglan 2016). The study of mechanical waves in different states of matter including pressure difference and sonic effect comes under acoustic. The acoustic word mean about hearing effect in general. The field of acoustic that deals with ultrasound. The range of frequency is above 20 kHz (Sarkar et al. 2016; Kumar et al. 2016). Ultrasound methods play a great role in giving information about the particle structure and molecular interactions which occur in liquid mixtures. The ultrasonic velocity and density on differ
