Study of Thermodynamic and Acoustic Properties of Niacin in Aqueous Hexylene Glycol and Propylene Glycol at Different Temperatures.

ABSTRACT: The densities and speed of sound for liquid mixtures containing vitamin B₃ (niacin) at 0.01, 0.03, and 0.05 mol·kg^-1 concentrations in aqueous propylene glycol and hexylene glycol at the variation of temperatures from 293.15 to 308.15 K have been measured using an Anton Paar DSA 5000 M. From volumetric experimental data, apparent molar volume (V _ϕ), partial molar volume (V _ϕ ⁰), and partial molar volume of transfer (ΔV _ϕ ⁰) are calculated along with the apparent molar isentropic compression (K _ϕ, S ), partial molar isentropic compression (K _ϕ, S ⁰), and partial molar isentropic compression of transfer (ΔK _ϕ ^0</
