  • Cymenol preparation by transfer dehydrogenation
    Patent number: 5068466
    Abstract: The invention relates to a process for the conversion of 8-hydroxymenthenes into 8-hydroxycymenes by reacting the 8-hydroxymenthenes in the liquid phase in the presence of a dehydrogenation catalyst, e.g. palladium and a hydrogen acceptor e.g. mesityl oxide. The process is preferably carried out at 80.degree.-150.degree. C. and in the presence of base. The process is particularly suitable for converting 8-hydroxy-p-menth-1-ene into 8-hydroxy-p-cymene.
