研究了电结晶银和掺锌电结晶银催化剂在1,2-丙二醇空气氧化制丙酮醛反应中的催化作用。采用10%掺锌电结晶银作催化剂,于500℃反应,丙酮醛产率为64.4%,达到了专利文献报导的催化剂最佳水平。本文还就掺锌有利于提高催化剂活性给出了解释。 The catalytic effect of electro-crystalline silver and zinc-doped electro-crystalline silver catalyst on the air oxidation of 1,2-propanediol to acetaldehyde was studied. Using 10% zinc-doped electro-crystallized silver as catalyst, the reaction was carried out at 500 ℃, the yield of pyruvaldehyde was 64.4%, which reached the optimum level of catalyst reported in the patent literature. This article also explained the zinc doping is helpful to improve the activity of the catalyst.
