Viscosity and density of polyethylene glycols and their mixtures
Autor: Damir Sagdeev
Density and viscosity of monoethylene glycol (MEG), diethylene glycol (DEG), and triethylene glycol (TEG) and their binary, (50%MEG+50%DEG), (50%MEG+50%TEG), (50%DEG+50%TEG), and ternary (33.33%MEG + 33.33%DEG + 33.34%TEG) mixtures were simultaneously measured... Viac o knihe

O knihe
Density and viscosity of monoethylene glycol (MEG), diethylene glycol (DEG), and triethylene glycol (TEG) and their binary, (50%MEG+50%DEG), (50%MEG+50%TEG), (50%DEG+50%TEG), and ternary (33.33%MEG + 33.33%DEG + 33.34%TEG) mixtures were simultaneously measured over the temperature range from 293 K to 465 K and at pressures up to 245 MPa using the hydrostatic weighing and falling-body techniques. The expanded uncertainty of the density, pressure, temperature, and viscosity measurements at the 95 % confidence level with a coverage factor of k = 2 is estimated to be 0.15 % - 0.30 %, 0.05 %, 0.02 K, and 1.5 % - 2.0 % (depending on temperature and pressure ranges), respectively. Tait-type equation of state (EOS) for pure MEG, DEG, and TEG was developed using the measured (p,¿,T) data. Theoretically based Arrhenius-Andrade and Vogel-Tamman-Fulcher type equation with pressure dependent coefficients was used to describe the temperature dependence of measured viscosities for pure polyethylene glycols.
