Aromatic halogenated compounds are used in the manufacturing of Li batteries (Jiang et al. [1]), in medicinal chemistry as antidepressant or drugs to reduce cholesterol (Wilcken et al. [2]; Poleto et al. [3]), and in the pharmaceutical industry due to the halogen bonding that they can form (Müller et al [4]). They are found in urban air arising from fuel combustion emissions (Calvert et al. [5]). Thus, it is interesting to study their thermophysical behavior and get a deeper view into their molecular interactions. (Iodobenzene + n-alkane) systems (heptane, decane, dodecane, tetradecane) were investigated in this work in terms of densities (𝜌), speeds of sound (𝑐) and excess molar enthalpies (𝐻m E) at a pressure (𝑝) of 0.1 MPa and the whole composition range (see Section 2). 𝜌 and 𝑐 were measured in the temperature (𝑇) range (288.15 to 308.15) K, whereas 𝐻m E were determined at 𝑇 = 298.15 K. Common excess properties and 𝑇 derivatives were calculated, correlated, and discussed (see Section 3).
