To obtain the optimum operation condition of batch fractionating for enrichment of 1,3,5-Mesitylene from C9 aromatic mixture, a batch fractionating model is established and used to simulate the process based on tridiagonal matrix method. A few of experiments are employed to examine reliability of computer simulation. The results of those experiments which are consistent with the simula- tion forecast show that the computer simulation could describe real separating process of C9 aromatic mixture by batch distillation. Finally, a comparative analysis of the separation efficiency under the influence of variety in the operation conditions is carded out and employed to choose the optimum operation condition.
