A brief statement of the density-based models utilized in the present research (ρ₁, T, P, P_ref, $y_2^{{}^{\prime }}$ , y₃ and a₀-a₆ are density of SC-CO₂, temperature, pressure, reference pressure, mole fraction in ternary system, mole fraction of cosolvent and adjustable parameters, respectively).

Model	Formula
MST53	$T\mathit{ln}\left(\frac{y_2^{{}^{\prime }}P}{P_{\mathit{ref}}}\right)=a_0+a_1{\rho }_1+a_{2}T+a_3{y}_3$
Sodeifian-Sajadian58	$\ln \left(y_2^{{}^{\prime }}\right)={(a}_0+\frac{a_1{\rho }_1}{T})\ln ({\rho }_1)+a_2{\rho }_1+a_3\ln (y_3\mathrm{P})$
González et al.52	$\ln \left(y_2^{{}^{\prime }}\right)=a_0\ln ({\rho }_1)+a_1\ln (y_3)+\frac{a_2}{T}+a_3$
Soltani-Mazloumi49	$\ln \left(y_2^{{}^{\prime }}\right)=a_0+\frac{a_1}{T}+\frac{a_2}{T}{\rho }_1-a_3\ln (\mathrm{P})+a_4\ln (y_3{\rho }_{1}T)$
