8–Methoxymenthan–3–ol was synthesised in a packed-bed flow reactor by the reaction of isopulegol and methanol in the presence of amberlyst-15 dry hydrogen form catalyst. Key parameters that affect isopulegol conversion and 8–methoxymenthan–3–ol formation were investigated and optimised. The reaction was found to be highly temperature-dependent, and to be less dependent of isopulegol: methanol molar ratio. Higher temperatures coupled with rapid flow rates resulted in higher isopulegol conversion. The optimum working temperature in the reactor was 57 °C and a maximum yield of 51.8% of 8–methoxymenthan–3–ol was obtained in 27.4 min at a flow rate of 3.6 cm3/min.

A series of monoterpenoids differing in the number of double bonds and the pattern of their substitution were tested in the liquid-phase noncatalytic oxidation with nitrous oxide (N2O). The structure of olefins has a significant effect on the oxidation route. In the case of terpenoids containing 1,1-disubstituted double bond, nor-carbonyl compounds are formed with high selectivity.
