摘要：

The liquid-liquid equilibria of N-methyl-alpha-pyrrolidone (NMP) with decane, undecane, dodecane, tridecane and tetradecane were measured by the synthetic method. The data were evaluated by using the NRTL equation and from the smoothed parameters the excess Gibbs energies and the excess enthalpies were calculated. Including the results of the first paper [1], the influence of the parameter ct on the value of the excess enthalpy and on the sign of the excess entropy is considered. Different possible correlations of the energy parameters of the NRTL equation are discussed.
