To study the influence of molecular structure on the volumetric properties of chloroalkanes, the densities of 1-chloropropane, 2-chloropropane, 1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane, and 2-chloro-2-methylpropane have been measured using a high-pressure high-temperature vibrating tube densimeter system over a temperature range from (283.15 to 328.15) K and a pressure range from (0.1 to 65.0) MPa. In the case of 1-chloropropane, 2-chloropropane, and 2-chloro-2-methylpropane the temperature ranges were (283.15 to 318.15) K, (283.15 to 308.15) K, and (283.15 to 323.15) K, respectively. The experimental densities have been satisfactorily correlated with temperature and pressure using the Tait equation. Moreover, using this equation and thermodynamic relations, isobaric expansibility, isothermal compressibility, and internal pressure have been calculated and analyzed in terms of molecular interactions and structure. The analyzed chloroalkanes follow the regular behavior of the liquids, and dipole dipole interactions are stronger in primary than in secondary or tertiary chlorinated compounds, as it could be expected.
