摘要：NOVELTY - The present invention discloses a preparation process of butanedione. Cheap isobutyl alcohol materials is heated to gasify and made to pass through catalyst layer with Ag, Cu, Zn, Al and other metals or their oxide to produce molecule rearranging reaction and oxidation in the air, so that butanedione is obtained. The product is refined to 98% over purity. ADVANTAGE - The present invention has continuous operation, cheap material and low production cost.
