Viscosimetric studies on 2-Methoxyethanol + 1, 2-Dimethoxyethane Binary mixtures from-10 to 80deg

摘要

The kinematic viscosities (v) were measured for nine binary solvent mixtures of 2-methoxyethanol (ME) +1, 2- dimethoxyethane (DME) at nineteen temperatures ranging from-10 to +80deg. The experimental data have been used to test some empirical equations of the type v=v(T), v=v(X_1) and v=v(T,X_1). The viscosities of all the mixtures increase from the values of pure DME to that of ME as the mole fraction of ME increases, and always yield a negative excess property (v~E) at all the investigated temperatures.
