EFFECT OF TWO-COMPONENT CATALYST ON THE PRODUCTION OF ACETALDEHYDE

New two-component catalysts for the co-synthesis of acetaldehyde and acetone based on acetylene hydration were prepared and studied. The waste KKF catalyst used in the synthesis of acetaldehyde was analyzed and its composition was determined. Based on the obtained analysis results, cadmium oxide, which is considered an active substance, was isolated from the KKF catalyst composition and various new brands of catalysts were prepared (KKM-1, KKM -2, KKM -3, KKM -4, KKM -5, KKM -6). Different brands of kaolin were used as the catalyst core. When these catalysts were tested, it was found that the KKM - 4 brand catalyst gave the highest yield in the synthesis of acetaldehyde and acetone. The mechanical strength of the catalysts, as well as chromatographic analysis and IR spectroscopy, were also studied.
