Volumetric and ultrasonic studies of molecular interactions of glycols in aqueous Niacin (vitamin B3) at different temperatures

At the temperature range of (293.15, 298.15, 303.15 and 308.15) K, the speed of sound and density values for ternary solution (Niacin+ water + Ethylene glycol (EG)/Diethylene glycol (DEG)/Triethylene glycol (TEG)) were measured at atmospheric pressure and (0.02, 0.04 and 0.06) mol·kg−1 niacin concentrations. The acoustic and volumetric properties of the mixture are analyzed though the calculated parameters i.e. Apparent Molar Volume (Vϕ),...
