Correlation and prediction of solubility of hydrogen in alkenes and its dissolution properties

Abstract In this work, solubility of hydrogen in some alkenes was investigated at different temperatures and pressures. Solubility values were calculated using the Peng–Robinson equation state. Binary interaction parameters fitting state on experimental data, Group contribution method Moysan correlations total average absolute deviation for these methods 3.90, 17.60 13.62, respectively. Because Alkenes is low, Henry’s law solutions investigated, too. Results calculation showed with increasing temperature, constant decreased. The temperature dependency constants ethylene propylene higher than to other alkenes. addition, Van’t Hoff equation, thermodynamic dissolution various calculated. indicated that spontaneous endothermic. enthalpy ( $${\Delta H}^{^\circ }$$ Δ H ∘ ) Gibbs free energy G}^{^\circ G systems 3.867 kJ/mol 6.361 kJ/mol, But almost not an entropy-driven process.
