Mehta, R. Chauhan] Ultrasonic velocities have been determined for binary mixtures of pyridine + n-alkanol (C1-C10) over the whole composition range at 25‡C. The excess isentropic compressibilities K S E and apparent molar isentropic compressibilities KΦ,s are estimated from these measurements. The K S E values are negative for all the systems over the complete mole fraction range except pyridine + decanol for which small positive values are obtained. The standard partial molar isentropic compressibilitiesK‡ of the alkanols are positive and increase linearly with the chain length of the alkanol molecules. It indicates that a methylene functional group makes a positive contribution to the expansion coefficient of a solute in these mixtures.
