Process for the preparation of 3,5-xylenol |
| abstract |
Isophorone is converted to 3,5-xylenol in the vapor phase in the presence of a heterogeneous catalyst comprising a particular combination of multiple rare earth metals on an alumina support or one or more rare earth metals in combination with one or more transition metals and/or one or more alkali or alkaline earth metals. Particularly good results are obtained with a catalyst comprising a naturally-occurring mixture of rare earth metals known as didymium in combination with potassium and cobalt promoters. |
