Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Menthol | HCID 1254 | — |
| Reactant | (-)-Menthol | HCID 16666 | — |
| Reactant | Piperitenone | HCID 381152 | — |
| Solvent | Water | HCID 962 | — |
| Product | 1-Methyl-4-isopropylcyclohexane | HCID 7459 | — |
Reaction Steps
The hydrogenation of the crude piperitenone is expediently carried out at temperatures at which as much d,l-menthol as possible is present in the menthol isomer mixture and no splitting off of water to form p-menthane takes place. Temperatures of 100° to 260°C, especially of 160° to 220°C, have proved advantageous.
