Example 1 was repeated using L-isopulegol with a purity of 99.9% by weight and 99.8% ee, which was introduced at a rate of 12.6 g/h (total amount 303 g) into the reactor at a hydrogen pressure of 40 bar. The main reactor (MR) was heated to 80° C., the postreactor to 75° C. L-menthol (99.8% ee) was obtained in an amount of 306 g corresponding to a rate of 12.8 g/h. The chemical purity of the L-menthol output is compiled in Table 2.
