ABSTRACT:
A process for producing menthone comprising dehydrogenating citronellol in the presence of a dehydrogenation catalyst at about 150 to about 260.degree. C in an atmosphere of hydrogen under a pressure of 0 to about 5 kg/cm.sup.2. G and a process for producing menthol. Since the dehydrogenation catalyst has a hydrogenating ability, an embodiment additionally includes the ability to ultimately produce menthol in the same reactor without separating the catalyst or adding additional or another catalyst to the system by simply changing the temperature and the hydrogen pressure. Embodiments also include producing menthone and also ultimately menthol utilizing geraniol or a mixture of geraniol and citronellol as a starting material again without catalyst separation or use of additional or another catalyst.
