As the production of medicinal acetaldehyde oxidation catalysts glacial acetic acid, should be able to accelerate both generate peracetic acid, but also to promote their rapid decomposition of the reaction system of traditional Chinese medicine to maintain a minimum concentration of glacial acetic acid. Since the reaction is the oxidation of acetaldehyde to acetic acid in the liquid phase, whereby the catalyst should be sufficiently soluble in the oxidizing solution, in order to display their catalytic action. The study found that variable valence metal (such as manganese, nickel, cobalt, copper) acetate or mixtures thereof can be used as a catalyst oxidation of acetaldehyde to acetic acid, the catalytic activity level of Co> Ni> Mn> Fe. Although cobalt acetate in acetic acid to generate the highest reaction activity in the oxidation of acetaldehyde, i.e., a cobalt salt of a pharmaceutically acceptable acetic acid catalyst generated a strong accelerating effect, but it does not meet the conditions of the rapid decomposition of peracetic acid, can cause pharmaceutically acceptable acetic acid accumulated in the reaction system, and therefore can not be applied. Manganese acetate as a catalyst, not only make the acetaldehyde oxidation reaction medicinal accelerated glacial acetic acid, glacial acetic acid, but also to ensure the formation and decomposition of medicinal basically the same speed, which is much higher than the yield of acetic acid catalyst other metals. Therefore, the commonly used industrial manganese acetate as a catalyst, and sometimes can be appropriate to add other metal acetate. The amount of manganese acetate, acetaldehyde about raw material (mass fraction) of 0.1% ~ o. 3%.
