Abstract
Isobaric vapor-liquid equilibrium (VLE) data for four binary systems of n-Undecane + Methyl dodecanoate,n-Dodecane + Methyl dodecanoate,n-Tridecane + Methyl dodecanoate and n-Tetradecane + Methyl dodecanoate were measured at 5.00 kPa by a Rose still, and the thermodynamic consistencies of all the measured data were checked. The results show that the experimental data satisfy the examination of thermodynamic consistencies. The experimental data were correlated by NRTL, UNIQUAC and Wilson acitivity coefficient model and the corresponding parameters for the three models were obtained. The three models with the obtained parameters were used to calculate the temperatures and the vapor compositions. The calculation results agree well with the experimental data.关键词
