1.The reasonableness of the numeric method for computing limiting concentration of light component in distillate is confirmed using the calculated results of the example.
2.A numeric method for computing limiting concentration of light component in the distillate of binary batch distillation under constant reflux ratio and hold-up in the column is introduced.
3.Conclusion: The best preparing process was: 4 times of soaking water as quantity as Armeniaca, extracting for 15 mins by ultrasound at 400 W power, collecting 1 time aqua armeniacae as quantity as armeniaca was a best technique.
