•Excess volumes and excess isentropic compressibilities investigated for o-chlorotoluene with 1-alkanol (C3–C7) mixtures.•Density and speed of sound data were analyzed interms of intermolecular interactions between studied components.•Formation of intermolecular hydrogen bonding between o-chlorotoluene and 1-alkanols was studied by FT-IR spectroscopy.
Excess volume (VE), isentropic compressibility (ks) and excess isentropic compressibility (ksE) for the binary mixtures of o-chlorotoluene with 1-propanol, 1-butanol, 1-pentanol, 1-hexanol and 1-heptanol over the temperature range from (298.15 to 308.15) K and at atmospheric pressure were derived from experimental density (ρ) and speed of sound (u) data. The measured excess properties were correlated with the Redlich–Kister polynomial equation. The calculated excess properties are discussed in terms of molecular interactions between o-chlorotoluene and 1-alkanol molecules and also with Fourier transform infrared (FT-IR) spectroscopy.
