“…The potential departure from the viscosity of PP in the research article by our team and the values presented in ref can be attributed to a couple of factors. First, there exists a discrepancy in the origin of the pure chemical utilized, as it is possible that different suppliers or manufacturing processes may yield variations in the properties of the substance.…”

“…It is important to mention that the viscometers used in refs , , and are not digital, and there are various sources of error that can lead to inaccuracies in their measurements. These error sources include (i) temperature control: both viscometers rely on the fluid being at a constant temperature, as viscosity is highly temperature-dependent.…”

In the current study, the density and viscosity of four binary fluids comprising propiophenone (PP) and 1-hexanol up to 1-nonanol systems were reported at various temperatures (293.15, 303.15, 313.15, and 323.15 K). The mixtures' excess molar volume (V m E ) and deviation in viscosity (Δη) were calculated, yielding negative values V m E for PP + 1-hexanol up to 1-octanol, and positive for PP + 1-nonanol solutions. Additionally, viscosity deviations were negative for PP and 1-alkanol at all temperatures. The findings suggest that molecular interactions are stronger in solutions containing shorter alcohols, while a rise in the alcohol hydrocarbon chain weakens the intermolecular forces. The applicability of the PC-SAFT was tested to correlate the mixture's density, and the agreement between the two sets of data is satisfactory. Moreover, a density functional theory (DFT) computational study confirmed the formation of hydrogen bonds and the strength between the component molecules. The experimental and derived thermodynamic properties agreed with those of the DFT theoretical model.
