摘要：
The xylene isomers (o -xylene, m -xylene and p -xylene) have been widely used as the raw materials to synthesize of many organic compounds in petrochemical industry and the additives in the gasoline and alternative fuels. The pendant drop method experimental setup was developed and the pure heptane was measured to test the accuracy and the reliability of the setup. To obtain their surface tension and remedy the shortage of the existing data, the o -xylene, m -xylene and p -xylene were measured in the temperature range from 303.15 to 393.15 K and 57 groups of the experimental data were obtained in the present work. These experimental data were used to fit the equations of the surface tension. The absolute deviation between the calculated surface tension from the correlation equation and the experiment results is within ±0.1 mN·m-1. The experimental data and calculated equations obtained in this paper can provide the basic thermal physical data for the engineering application of o -xylene, m -xylene and p -xylene. © 2016, Xi'an Jiaotong University.
