摘要

于阳离子隔膜的电解槽中,以MnO2/Mn2+电对作催化氧化的媒介,在超声波高频振荡下,电生成的MnO2颗粒以几十nm至几μm尺寸分散在溶液中.随后将甘油电化学氧化为甘油醛,该MnO2/Mn2+电对催化活性的选择性高,电流效率可达97.4%.

Abstract

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 %.
