Density, Viscosity, and Excess Properties of Aqueous Solution of 1,3-Dimethyl-2-imidazolidinone (DMI)

A complete study of thermophysical properties concerning the 1,3-dimethyl-2-imidazolidinone (DMI) + water binary system is realized. Density, speed sound, dynamic viscosities, and refractive index measurements have been performed at atmospheric pressure, using a vibrating tube densitometer, falling ball viscosimeter, refractometer for pure DMI, water, aqueous solutions from 278.15 to 323.15 K. The thermal expansion was calculated density data. Excess Gibbs energy flow corresponding excess entropy were also considering viscosity molar (volume, expansion, flow, square index) calculated, Redlich–Kister equations applied correlate analysis behavior allows us identify most relevant molecular interaction in mixtures rich DMI water. Our results show that can be classified as liquid structure maker molecules are certainly inserted network finite dilution.
