Mixing Properties of Binary Liquid Mixtures of Cyclopentane with Branched Alcohols at Different Temperatures

Densities, rho, and speeds of sound, u, of cyclopentane with 2-methyl-1-propanol, 3-methyl-1-butanol, and 2-methyl-2-butanol binary liquid mixtures have been measured over the whole composition range at atmospheric pressure at temperatures: 288.15, 298.15, and 308.15 K. Excess molar volumes V-m(E), isentropic compressibility K-S, and their excess counterpart excess isentropic compressibility K-S,m(E) have been calculated from experimental densities and speeds of sound. Apparent molar volume, V-phi,V-i partial molar volume, V-i, and apparent molar compressibilities have been calculated from the experimental density and speeds of measurements.
