موضوع به انگلیسی:Ultrasonic and volumetric behaviour of glycols with sodium
ethylparaben in aqueous medium from T = 293.15 to 308.15 K at
atmospheric pressure
بخشی از متن:Volumetric and acoustic analysis is set in motion to inspect the sodium ethylparaben interaction with ethylene
glycol, and propylene glycol as a function of temperature. The estimation of apparentmolar volumeand apparent
molar isentropic compression of glycols in aqueous solutions of sodium ethylparaben has been done by
employing densities and speed of the sound measurements at p=0.1MPa and T=293.15 to 308.15 K. The partial
molar volume, partialmolar isentropic compression, partialmolar volume of transfer and partial molar isentropic
compression of transfer have been scrutinized from the density and speed of sound data. The partial molar
expansibility is also determined. The data estimated from transfer properties is exercised to examine coefficients
of pair and triplet interaction. Further, the results are explicated in terms of co-solutes and solvents associations

sodium ethylparaben
