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