Densities and derived thermodynamic properties of (2-methoxyethanol + 1-propanol, or 2-propanol, or 1,2-propandiol) at temperatures from T = (293.15 to 343.15) K

Densities of the binary liquid mixtures of (2-methoxyethanol + 1-propanol, or 2-propanol, or 1,2-propandiol) have been measured over the entire range of compositions at temperatures from (293.15 to 343.15) K and ambient pressure 81.5 kPa, using a vibrating-tube densimeter. The excess molar volumes VmE, thermal expansion coefficients α, and their excess values αE, and isothermal coefficient of pressure excess molar enthalpy ∂HmE/∂PT,x, were calculated from experimental densities. The excess molar volume is positive for (2-methoxyethanol + 1-propanol) and becomes more positive with increasing temperature. The excess molar volume for (2-methoxyethanol + 2-propanol) shows a S-shaped dependence on composition with positive values in the 2-propanol rich-region and negative values at the opposite extreme. With increasing temperature from (293.15 to 313.15) K, it increases but beyond this range with increasing temperature from (313.15 to 343.15) K it decreases. The excess molar volume is negative for (2-methoxyethanol + 1,2-propandiol) and becomes more negative with increasing temperature. The excess molar volumes were correlated with a Redlich–Kister type equation.
