Joint Synthesis Of Acetone And Acetaldehyde From Acetylene

Аннотация

The study investigated the possibility of using catalysts based on compounds of cadmium, zinc and other elements filled with orbital electrons d10, having several polyfunctional properties, as well as promoted by compounds of various metals in the hydration reaction of acetylene and its derivatives. The acetylene hydration reaction yields acetaldehyde or acetone depending on the composition and nature of the catalyst used under the same conditions. In particular, the formation of acetylene at 360-440 0C in the presence of a catalyst from cadmium fluoride-containing 20% CdF2, 5.0% AlF3, 75% Al2O3: acetaldehyde formation when reacted with water = 1: 3-1: 5, cadmium fluoride, It has been found that using catalysts containing zinc, iron, nickel, cobalt compounds instead of aluminium fluoride, the process leads to the formation of acetone.
