In the study, the catalytic hydration reaction of acetylene in the presence of catalysts based on local raw materials was carried out under stationary conditions in a flow reactor made of stainless steel with a diameter of 25 mm and a height of 1000 mm. The reaction products were analyzed chromatographically. In the presence of the created fluoride catalyst, the conversion of acetylene is 75-80%, the yield of acetaldehyde is 93%, the yield of acetone is 2.5%. The reason for the high activity of cadmium-zinc-aluminum catalysts is explained by the fact that they form the active center of ox fluorides on the surface of the catalyst. The effect of temperature, volumetric velocity, acetylene: water ratio, etc. on acetaldehyde yield in the presence of the selected catalyst was studied. When the effect of temperature was studied in the range of 300-440oC, an increase in acetylene conversion and a decrease in acetaldehyde selectivity were found with increasing temperature. X-ray studies have established that cadmium-chromo-fluoro-aluminum catalysts have high activity in polymorphic-crystalline state.

The vapour-phase hydration of acetylene with the formation of acetone on polyfunctional catalysts has been studied. The process parameters have been found that ensure the production of acetone with high selectivity and conversion of acetylene. As a result of studying the effect of temperature on the yield of acetone, it was found that in the temperature range of 360-5000C the dependence between the reaction yield and temperature is extreme and at 4500C the yield is maximum. Based on the study of the kinetic laws of the reaction, the mechanism of acetone formation in the presence of a given catalyst based on the kinetic equation of the reaction to obtain acetone by the catalytic hydration of acetylene and the results of experimental and qualitative and quantitative compositions of reaction products.
