Pyruvaldehyde was synthesized with acetone or 1,2 propanediol as starting material respectively.With n∶n=1 00∶0 79,3 0-4 0 g potassium chlorate as catalyst,and water and glacial acetic acid as solvent,refluxing on water bath of 60-75 ℃ for 4 h,bromoacetone was obtained in 63 5% yield.

分别用丙酮和 1，2 丙二醇做原料合成了丙酮醛。n∶n =1 0 0∶0 79，加入 3 0～4 0g氯酸钾做催化剂，水和冰醋酸做溶剂，水浴温度为 6 0～ 75℃，回流 4h ，制得产率为 6 3 5 %的溴丙酮。V∶V =11 9∶1 0 ，通入空气，在 6 5～ 70℃反应 5～ 8h ，制得产率为 5 9 6 %的丙酮醛。
