CO_2 dissolution phenomena are important issues in enhanced oil recovery (EOR). Fundamental mechanism of them, however, is not clarified. In this study, CO_2 dissolution in cyclohexane (C_6H_<12>) was investigated by molecular dynamics simulations. Although CO_2 seems to be dissolved into C_6H_<12> which shows distinct difference to the case of CO_2/H_2O, aggregation of CO_2 molecules was observed under the condition of high CO_2 mole fraction. Furthermore, dissolution process in the CO_2/C_6H_<12> interface was enhanced in the case of supercritical CO_2, compared with that of liquid CO_2.
