Abstract: Reaction of catalytic hydrogenation of natural compounds (limonene, α-pinene, β-pinene, camphene, 3-carene) on СuО-Al2O3, NiО-Cr2О3 catalysts and on Pt/γ-Al2O3 for comparison has been studied at elevated temperatures (180-350 oC) under pressure (2.5-3 atm) in a flow-through type catalytic set-up. Qualitative and quantitative analysis of the reaction products were conducted by the chromato-mass spectrometry method. The process goes most effectively and with high selectivity when used CuO-Al2O3 catalyst. Accordingly, either isomeric mixture of para-menthanes, or para-1-menthene is preferentially formed from limonene depending on the degree of the catalyst activity; a mixture of cis- and trans-pinanes with the latter isomer being predominant is formed from α- and β-pinenes; isomeric mixture of exo- and endo-isocamphanes in equal quantities is formed from camphene; and 1,1,4-trimethylcycloheptane, from 3-carene. p-Cymene and α-pinene are formed preferentially on catalyst NiO-Cr2O3 without hydrogen from limonene and β-pinene.
