Reaction Steps
165 g 4-(3-methyl-but-2-enyl)-phenol, 2 wt. % Raney nickel-iron (composition of the catalyst: 45% nickel, 3% aluminium, 8% iron; water content 44%) are initially introduced into a stirred autoclave with a gassing stirrer. Hydrogenation is carried out for 6 hours at 170° C. under a hydrogen pressure of 20 bar. After filtration, 165 g of crude product are obtained. 158 g 4-isoamylcyclohexanol (b.p.: 65° C., 0.6 mbar), which has the following composition: 33.1% cis-4-isoamylcyclohexanol and 66.3% trans-4-isoamylcyclohexanol, are obtained by distillation of the crude product.
