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

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.
