Abstract�� The experimental study for purification of peach aldehyde by vacuum batch distillation,as well as the heat sensitivity of the product,is carried out.The optimal operation condition for purification of peach aldehyde is that:the pressure of operation system is less than 4\^0 kPa and temperature of the reboiler is less than 180 �� with variable reflux ratio.The concentration and average yield of the product is up to 99\^0% and 72\^4% respectively.Meanwhile,the impurity of n-octanol is less than 5��10~(-6).The experimental study is simulated by Hysis Plant 2.2 and it agrees well with the simulation.This can give some suggestion for the purification process.
