Determination and Correlation of the Densities and Viscosities of Methanol-Glycol Binary Mixtures

Densities and viscosities of methanol and glycol mixtures at 288. 154303. 15 K were measured using calibrated pycnometer and Ubbelohde-type capillary viscometer. Excess molar volumes and excess viscosities of the binary system were calculated respectively and were found negative for all compositions and temperatures under investigation. The excess molar volumes were related to compositions by polynomial regression and the excess viscosities were related to compositions by Redlick-Kister equation.
