Densities and Viscosities of Niacin + 3-Picoline + Water Mixtures from (293.15 to 343.15) K

Abstract

The densities and viscosities of niacin + 3-picoline + water mixtures have been determined experimentally at temperatures from 293.15 K to 343.15 K. The apparent molar volumes were calculated from experimental measurements. Results were fit to obtain the adjustable parameters and standard deviations between the measured and fit values.

Densities and Viscosities for Binary Mixtures of Chlorinated Polypropylene with Toluene, Tetrahydrofuran, Chloroform, Carbon Tetrachloride, and 2-Butanone at (298.15, 308.15, and 318.15) K

“…The apparent molar volume of CPP repeat unit, V φ,2 , is given by the equation [18][19][20] The relation between apparent molar volume of CPP repeat unit, V φ,2 , and its molality, m, is given by [21][22][23] where S V is the slope. V φ,2 0 is standard partial molar volume of the CPP repeat unit.…”

“…The relation between apparent molar volume of CPP repeat unit, V φ ,2 , and its molality, m , is given by − where S V is the slope. is standard partial molar volume of the CPP repeat unit. Since the partial molar quantity of pure solvent is equal to its molar quantity, the physical quantity that corresponds to is the molar volume of pure solvent, V m , which is a character parameter of pure solvent. is obtained by fitting eq 4 to experimental results using a least-squares regression method.…”

Density and Viscosity of LiCl, LiBr, LiI and Kcl in Aqueous Methanol at 313.15K

“…[2][3][4][5][6][7][8][9] Viscosity is one of the important transport properties of electrolyte solutions and belongs to a dynamic state property, while density is one of the key thermodynamic features of electrolyte solutions and contributes to an equilibrium property. [10][11][12] Researchers have explored the use of density and viscosity of mixtures to derive thermodynamic properties like dynamic viscosity, kinematic viscosity, deviations in dynamic viscosity, excess molar volume, surface tension deviation, apparent molar volumes, etc. [13][14][15][16] .…”

Solid–Liquid Equilibrium and Phase Diagram for the Ternary Succinic Acid + Glutaric Acid + Water System

“…The densities of the equilibrium liquid phase were measured by the pycnometer method. 21 All of the measurements were repeated at least three times, and the average data of corresponding experimental measurements were considered to be the solubility data. The related standard uncertainty of measured solubilities is estimated as u r (x) = 0.02, and the experimental uncertainty is mainly due to temperature measurements and sampling procedure during experimental measurements.…”
