METHOD AND CATALYST FOR DEHYDROGENATION OF SECONDARY CYCLIC ALCOHOLS AND METHOD OF PRODUCTION OF SUCH CATALYST Russian patent published in 2002 - IPC

FIELD: 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
