Reaction Steps

85 g 4-(3-methyl-but-2-enyl)-phenol, 3 wt % rhodium-on-active charcoal (Rh content, based on the weight of the dry catalyst: 5%; water content about 50%) are initially introduced into 500 ml isopropanol and 9.6 g methanesulfonic acid in a stirred autoclave with a gassing stirrer. Hydrogenation is carried out for 5 hours at 80° C. under a hydrogen pressure of 10 bar. After filtration, 85 g 4-isoamylcyclohexanol are obtained as a crude product. After distillation, 80 g 4-isoamylcyclohexanol, which has the following composition: 67.6% cis-4-isoamylcyclohexanol and 31.8% trans-4-isoamylcyclohexanol, are obtained.
