Variation of Densities, Refractive Indices, and Speeds of Sound with Temperature of Methanol or Ethanol with Hexane, Heptane, and Octane

In this work we present experimental values of the density, refractive index, and speed of sound of the binary mixtures methanol or ethanol plus hexane, heptane, and octane at the temperatures 303.15, 308.15, 313.15, and 318.15 K and at atmospheric pressure, as a function of mole fraction. The experimental results have been fitted as a funtion of composition. A comparison with other experimental data in the literature has been made.
