Glyceraldehyde is prepared by using MnO2/ Mn2+as the media in a cationic membrane electrolytic cell.Under ultrasonic high-frequency oscillation,the electro-generated nanometer MnO2 dispersed in the solution with several tens nm till several micron.Then the MnO2 is used for selective oxidation of glycerine to glyceraldehydes.The catalyzing selectivity of MnO2/ Mn2+is high and the current efficiency may account to 97.4 %.
