Catalytic activity of the VIII group metals in the hydrogenation and isomerization of α- And β-pinenes

The kinetic regularities of the liquid-phase hydrogenation and isomerization of α- and β-pinenes over the Pd/C, Ru/C, Rh/C, Pt/C, and Ir/C catalysts were studied at temperatures ranging from 20 to 100 °C and at hydrogen pressures of 1-11 bar using n-octane as the solvent. The hydrogenation and isomerization of α- and β-pinenes occur simultaneously on the Ru/C, Rh/C, Pt/C, and Ir/C catalysts, and the reaction mixture contains the products of double bond hydrogenation, viz., cis- and trans-pinanes. The Ru, Rh, and Pd metals have a higher catalytic activity in β-pinene isomerization than Ir and Pt. Among the VIII Group metals studied, the Pd-based catalyst has the highest catalytic activity in double bond isomerization of α- and β-pinenes. The general scheme of the mechanism of hydrogenation and isomerization of α- and β-pinenes on the Pd/C catalyst was proposed.

Dehydration Studies of α- and β-Ionol. I With Hexamethylphosphoric Triamide

α-Ionol (2) when heated under reflux with hexamethylphosphoric triamide gave principally one product (1'E)-6-(buta-1',3'-dienyl)-1,5,5-trimethylcyclohex-1-ene (4a) together with trace quantities of the (1'Z)-isomer (4b).Under similar conditions β-Ionol (3) gave as major products (6E,2'E)- and (6Z,2'E)-6-(but-2'-enylidene)-1,5,5-trimethylcyclohex-1-ene (1a) and (1b) together with smaller quantities of (1'E)-1-(buta-1',3'-dienyl)-6,6-dimethyl-2-mehtylenecyclohexane (8) and 1,1,6-trimethyl-1,2,3,4,5,6-hexahydronaphtalene (9).Minor products from this reaction includedthe isomeric trienes (1c) and (1d).Reaction pathways are suggested for the formation of all identified products.
