Joint synthesis of acetone and acetaldehyde from acetylene
Abstract
The study investigated the possibility of using catalysts based on compounds of cadmium, zinc and other elements filled with d10 orbital electrons with a number of polyfunctional properties, as well as promoted by compounds of various metals in the hydration reaction of acetylene and its derivatives. The hydration reaction of acetylene produces 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°C in the presence of cadmium fluoride catalyst containing 20 % CdF2, 5,0 % AlF3, 75 % Al2O3 formation of acetaldehyde when reacting with water = 1: 3 - 1: 5, cadmium fluoride, it was found that when catalysts containing zinc, iron, nickel, cobalt compounds are used instead of aluminum fluoride, the process leads to the formation of acetone.
