Abstract Binary vapour-liquid equilibrium of thymoquinone and carbon dioxide at the isothermal conditions was carried out at temperature 323.15 K and pressures from 6 to 10 MPa. The experimental data were fitted to the Soave-Redlich-Kwong equation of state. Results could be used for selection of process parameters in separation of volatiles from raw oil or for evaluation of existing separation technologies.

The synthesis of dimethyl carbonate (DMC) by oxidative carbonylation of methanol with PdCl2 as a catalyst was investigated in the room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]). The products were recovered in situ using supercritical carbon dioxide. Enhanced selectivity of DMC over this catalyst was observed in the synthesis in [bmim][PF6] compared with the situation without the ionic liquid (IL). The mixture of catalyst and [bmim][PF6] could be recycled.
