The separation of ethyl acetate-acetone mixtures from waste liquid in superfine ammonium perchlorate preparation was simulated. The effect of continuous distillation process parameters, including the stage numbers of distillation column, the number of feed stage, reflux ratio, and the amount of top products on ethyl acetate-acetone separation was investigated by using RadFrac module of Aspen Plus software. The results show that when the flow rate of ethyl acetate-acetone mixed solvent is 3 kg/h, the optimum operation parameters are as follows: the stage numbers for distillation column is 40; the feed stage is No.16; reflux ratio (volume ratio) is 5 and the flow of top products is 0.28 kg/h. Under the optimized parameters, the mass fraction of ethyl acetate at the bottom is enhanced to 99.67%, and the yield can achieve 99.40%; the mass fraction of acetone at the top is enhanced to 94.25%, and the yield can achieve 96.66%. The result of simulation provides fundamental guide for the experimental study and industrialization design.
