Reaction Steps

330 g 4-(3-methyl-but-2-enyl)-phenol, 3 wt. % ruthenium-on-active charcoal (Ru content, based on the weight of the dry catalyst: 5%; water content about 50%) are initially introduced into 570 ml isopropanol in a stirred autoclave with a gassing stirrer. Hydrogenation is carried out for 5 hours at 100° C. under a hydrogen pressure of 130 bar. After filtration, 329 g 4-isoamylcyclohexanol are obtained as a crude product. After distillation, 316 g 4-isoamylcyclohexanol, which has the following composition: 53.8% cis-4-isoamylcyclohexanol and 44.9% trans-4-isoamylcyclohexanol, are obtained.
