Densities and Viscosities of Poly(ethylene glycol) 4000 + Diammonium Hydrogen Phosphate + Water Systems
The densities and viscosities of binary and ternary solutions of the poly(ethylene glycol) 4000 (PEG4000) + diammonium hydrogen phosphate + water system were determined at different temperatures [(298.15, 303.15, 308.15, 313.15, and 318.15) K]. The measured density and viscosity data of all the bi...

| description | The densities and viscosities of binary and ternary solutions of the poly(ethylene glycol) 4000 (PEG4000)
+ diammonium hydrogen phosphate + water system were determined at different temperatures [(298.15,
303.15, 308.15, 313.15, and 318.15) K]. The measured density and viscosity data of all the binary and
ternary systems were fitted to available empirical correlations, for the corresponding temperatures. The
density data show a linear variation with mass fraction of the polymer for all temperatures. The viscosity
data of all the solutions were correlated as a function of their mass fraction, using a nonlinear equation, for
the five different temperatures covered in the present work. Densities and viscosities of PEG4000-diammonium
hydrogen phosphate two-phase systems have been measured at (298.15, 303.15, 308.15, 313.15, and 318.15)
K. The tie line lengths (TLL) of the aqueous two-phase systems have also been estimated, and the effect of
the physical properties on the TLL is also reported. |
