실험 절차

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.
