Liquid Densities, Kinematic Viscosities, and Heat Capacities of Some Alkylene Glycol Dialkyl Ethers

Liquid densities and heat capacities at 1 MPa, and kinematic viscosities at atmospheric pressure of monoethylene glycol diethyl ether, diethylene glycol diethyl ether, diethylene glycol dibutyl ether, triethylene glycol dibutyl ether, and dipropylene glycol dimethyl ether were measured in the temperature range (283.15 to 423.15) K. For each substance, experimental data were correlated with temperature using empirical polynomial equations. The experimental data of kinematic viscosity and heat capacity were used to evaluate the predictive capability of some estimation methods of the literature.
