摘要
In order to study the aggregation of CO2 and organic liquid molecules in the binary systems of CO2+ organic liquid at near critical and supercritical condition of CO2, the radial distribution function of CO2-organic liquid molecules and organic liquid-organic liquid molecules in the liquid phase of the CO2+ organic liquid systems is calculated by molecular dynamic simulation in this work and compared with the results of our previous works. The results of the research show that the aggregates of CO2-CO2 molecules, CO2-organic liquid molecules and organic liquid-organic liquid molecules are coexisted in the liquid phase of CO2+ organic liquid system, respectively.
