Densities and Viscosities of Seven Glycol Ethers from 288.15 K to 343.15 K

Abstract

Densities and viscosities of seven glycol ethers consisting of 1-methoxy-2-propanol, 3-methoxy-1-butanol, ethylene glycol dimethyl ether, ethylene glycol diethyl ether, diethylene glycol dimethyl ether, ethylene glycol tert-butyl methyl ether, and diethylene glycol diethyl ether were measured from 288.15 K to 343.15 K at atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were measured with an automatic Ubbelohde capillary viscometer. The estimated uncertainties of the measurements were ±0.1% for density and ±0.9% for viscosity. The data were correlated using simple expressions and were also used to develop a model for the viscosity based on the Hildebrand fluidity equation.

Computational Chemistry Study of Molecular Interactions in CO₂-loaded Diethylene Glycol, Triethylene Glycol, and Diethylene Glycol Dimethyl Ether

“…b) Two approaches were used to determine the density values. 19) 298.15 14) 298.15 15) 298.15 16) 299.35 19) 308. 15 18 2 in DEGDME is much higher, probably because the polarity of a methoxy group is generally weaker than that of a hydroxyl group, resulting in competitive CO2 absorption between the methoxy groups and ether bonds in DEGDME.…”

Excess properties and spectral studies for binary system tri-ethylene glycol + dimethyl sulfoxide

“…Up to the present, organic liquids have been excellent candidates to absorb SO 2 , a major pollutant source from industrial processes [1], because of its high efficiency, low cost and none byproducts [2][3][4]. For example, DMSO was used intensively in SO 2 absorption because of its low volatility and good affinity with SO 2 [5,6].…”
