“…al. [8][9][10], to adjust their models when relating cohesive energy, enthalpy of vaporization, and internal pressure in the calculation of SP values of asphaltene and crude oils. Interfacial tension wettability, ratio of isobaric to isothermal compressibility factors, and the boiling points of nonpolar liquids are thermodynamic parameters can be calculated by determining the SP [11].…”

Two different paths were followed to calculate the solubility parameters (SP) of 133 alkanes. The first approach calculates SP from the points of view of internal pressure and residual energy, whereby Soave‐Redlich‐Kwong and Peng‐Robinson equations of state (EOSs) are employed with and without the volume‐shift correction. In the second approach, the cohesive energy concept is used and the saturation pressure and saturated liquid molar volume are separately computed by different models and coupled to one another. The results indicated that Approach 1 predicts SP with an error of 2.24 %, which is in the same order as that of Approach 2 but slightly better. The performance of Approach 1 was assessed by estimating the SP values of 33 substances from various families and comparing the results to an EOS‐based study.

Macroalgae-derived oils offer a sustainable and environmentally friendly alternative to conventional mineral oils and additives in lubricant formulation. Their favorable fatty acid profiles can contribute to mitigating the environmental impacts caused by using fossil-based products. This study evaluates the potential of Sargassum spp. oil, collected from the Mexican Caribbean, as a lubricity-enhancing additive in synthetic base oils. The impact of Sargassum spp. oil on viscosity and tribological performance was analyzed. The results indicated that Sargassum spp. oil has potential as an anti-wear additive since a formulation using 10% v/v Sargassum spp. oil in a synthetic lubricant (PAO6) resulted in a wear scar diameter value of 703.03 ± 15.56 µm, which is about 10% lower than PAO6 used as commercial synthetic control. Additionally, the formulation significantly enhanced the viscosity index, with a value of 169, which was notably higher than the control (137). The parameter of the coefficient of friction was significantly reduced from 0.1 to 0.08 (about 27%) when using the formulation with 10% v/v Sargassum spp. oil. These findings underline the potential of algae oils as additives in synthetic lubricants, promoting a transition towards greener products and reducing the environmental impact derived from conventional formulations of polyalphaolefins and esters.
