摘要: In order to investigate the effect of organic liquidmolecular structure and the intermolecular force operatingwith CO2 molecules and organic liquid molecules on interfacial tension (IFT) between CO2 and organic liquid at the first contact, the interfacial tension between CO2 and hexane, octane, ethanol and cyclohexane at different temperatures and pressures ismeasured by using the pendant drop method and the axisymmetric drop shape analysis (ADSA). The results show that the interfacial tension between CO2 and organic liquids is affected by the polarity and the structure of the organic liquid molecule obviously. The intermolecular force operating within CO2 molecules or organic liquid, and that between CO2 and organic liquids molecules play a dominate role on the interfacial tension between CO2 and the organic liquids.
