Acoustical parameters of polyethylene glycol/water mixtures

Abstract

Ultrasonic velocity (v) and density (d) have been measured for polyethylene glycol/water mixtures at 30°C. The adiabatic compressibility (βad), molar compressibility (β), specific acoustic impendance (Z), Rao number (R) and van der Waals constant (b) have been computed. The variations of v, d, βad, β, Z, R and b with mole ratio of water/ether group oxygen have been studied. The association between the components and the formation of tetrahydrate have been reported. © 1995 the Indian Academy of Sciences.
