Abstract
Densities (ρ) and ultrasonic speeds (u) of the binary liquid mixtures of Tripropylene Glycol Monomethyl Ether (TPGMME) and 1-haptanol have been measured as a function of composition at temperature range of 288.15 to 318.15 K and atmospheric pressure. The measurements have been carried out using an Anton Paar density and speed of sound analyser DSA 5000. Thermodynamic properties like excess molar volumes, isentropic compressibility and molar isentropic compressibility have been calculated by using densities and speed of sound data at various temperatures. Value for excess molar volume is positive for (TPGMME) and 1-haptanol over the entire mole fraction range, and increase with increasing temperature.
