Abstract
By using polyoxyethylene nonylphenyl ethers as the stationary phase, the retention volume of some hydrocarbons was measured at varying temperature by gaschromatography. The activity coefficient and the excess thermodynamic functions of hydrocarbons were calculated from the retention values obtained. The results were available to interpret the interaction between hydrocarbons and polyoxyethylene nonylphenyl ethers on thermodynamic basis.
