in this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing n,n-dimethyl acetamide (dmac) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 k. the results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. deviation values of heavy alcohol have more positive and less negative excess...

experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-bd, in2-ethyl-1-hexanol, 2eh, were reported for various mole fractions and temperatures (298.2-308.2) kand they were used to calculate dielectric parameters such as kirkwood correlation factor, excesspermittivity and bruggeman parameter. these parameters were used to carry out temperaturedependent die...

In this study the intermolecular potential energies of some environment-friendly industrial HFC refrigerants were obtained through the inversion method which is based on the corresponding states principle. These potentials were later employed in calculation of transport properties (viscosity, diffusion, thermal conductivity and thermal diffusion factor) of some binary and ternary refrigerant mi...

the solubility of naproxen in binary mixtures of polyethylene glycol 200 (peg 200) + water at the temperature range from 298.0 k to 318.0 k were reported. the combinations of jouyban-acree model + van’t hoff and jouyban-acree model + partial solubility parameters were used to predict the solubility of naproxen in peg 200 + water mixtures at different temperatures. combination of jouyban-acree m...

This paper presents the experimental investigations conducted on a vertical closed loop pulsating heat pipe (VCLPHP) to evaluate the thermal performance. The values of thermal resistance and heat transfer coefficient obtained in the experimentation is used as evaluation parameters. The VCLPHP used has capillary tubes having an inner diameter of 2mm and outside diameter 3mm and bent into 5 turns...

Densities, structural effects and viscosities of binary nonelectrolyte systems including nitrobenzene + 2-propanol, 2-butanol and 2-pentanol at temperatures (293.15 to 323.15) K and normal atmospheric pressure were measured using an Anton-Paar SVM 3000 stabinger viscometer. Excess molar volumes  and viscosity deviations Δη were calculated and correlated by the Redlich-Kister equation t...

In this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing N,N-dimethyl acetamide (DMAc) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 K. The results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. Deviation values of heavy alcohol have more positive and less negative excess...
