Abstract. The hydrogenation of a-pinene was investigated in a batch reactor over 4 wt% palladium on carbon (Pd/ C) catalyst in temperature range of 50–90 8C and 2–11 bar of hydrogen pressure using n-octane as a solvent. The reaction network involves hydrogenation of a-pinene to two stereoisomers. The reaction kinetics was established in conditions free from diffusional limitations. The …
