Abstract: methods of dehydrogenation of secondary cyclic alcohols in presence of catalyst containing zinc and calcium carbonate at elevated temperature in gas phase where dehydrogenation is effected in presence of hydrogen. SUBSTANCE: active components of catalyst used for realization of this method include 30 to 60+ACU- of zinc oxide and 40 to 70+ACU- of calcium carbonate in calcite modification. Invention discloses also dehydrogenation catalyst and method of its +AFs-production. EFFECT: possibility of obtaining cyclic ketones, cyclohexanone in particular at higher selectivity and higher yield reducing to minimum formation of splitting and aromatic byproducts+ADs- enhanced strength of tablets at frontal and lateral compression, thus increasing intervals for replacement of catalyst. 14 cl, 2 tbl, 3 ex, 2 test ex

Abstract: chemical technology. SUBSTANCE: invention relates to method of synthesis of cyclohexane oxidation substances by catalytical liquid-phase oxidation with oxygen-containing gases. Liquid cyclohexane is passed by countercurrent procedure through reaction zone which is separated for some communicating chambers by perforated plates. Oxygen-containing gas is added along reaction zone through nozzle holes that are uniformly distributed by cross section. As result, no formation of continuous gaseous phase in reaction zone is occurred. Distances of gas feeding are 0.1-3-fold diameter of reaction zone being gas is added to reaction zone where oxygen from preceding addition is not consumed completely. Temperature in reactor is 120-180 C, pressure is 5-30 bars. EFFECT: decreased formation of by-side compounds, increased productivity of reactor. 10 cl, 1 tbl, 2 ex
