摘要：
An integral method to determine infinite dilution activity coefficients (gamma(i)infinity) from data sets of finite concentration activity coefficients is proposed for binary systems. This method is based upon the integration of the experimental dependence of ln gamma(i)/x(j)2 over different composition ranges. The limiting behavior of this function is analysed, in order to improve the precision of its integration. The accuracy of this method is demonstrated by the calculation of gamma(i)infinity for several systems.
