P-cymenol preparation by transfer dehydrogenation |
| 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 80-150°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. The reaction products are of value as intermediates in the preparation of fragrance chemicals. |
