The densities of several organic liquids (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-methyl-1-propanol, 2-butanol, 1-pentanol, 2-methyl-1-butanol, 1-hexanol, 1-heptanol, benzene, toluene, p-xylene, n-heptane, and n-octane) and their binary mixtures (methanol+1-propanol, methanol+2-propanol, ethanol+1-butanol, ethanol+2-methyl-1-propanol, ethanol+1-hexanol, 1-pentanol+1-hexanol, benzene+toluene, and benzene+n-heptane) have been measured by use of a pycnometer in the region 20℃ to 70℃ under atmospheric pressure. By using the present data, the corresponding states principle coupled with the molecular shape factors has been ascertained to be successful for the correlation of the molar volumes of pure organic liquids. The molar volume of a binary mixture could also be correlated with the corresponding states principle by using the pseudo-critical properties. The densities of 1-butanol containing calcium chloride have been determined as a supplement to a previous study. The density data obtained at given temperatures and molalities could be represented by an empirical equation proposed previously. The recommended values for the coefficients in empirical equations are presented for the calculation of densities of methanol, ethanol, 1-propanol, 2-propanol, and water containing calcium chloride.
