الإجراء التجريبي

In a 500-mL autoclave were added 100.0 g (0.65 mol) of the 1-isopulegol obtained in Example 44 and 0.4 g of Raney nickel in a nitrogen atmosphere. Hydrogenation was conducted at a hydrogen pressure of 2.5 MPa and 70° C. for 10 hours. The reaction mixture was filtered, followed by distillation to obtain 94.8 g (0.61 mol, 100% e.e.) of 1-menthol.
