PROCESS FOR THE HYDROGENATION OF ALKYLARYL KETONES

摘要

The present invention pertains to a process for the hydrogenation of alkylaryl ketones, which process comprises contacting a feed comprising the alkylaryl ketones and of from 0.5 to 30% by weight of phenolic compounds with hydrogen in the presence of a heterogeneous hydrogenation catalyst. The invention further relates to a process for preparing a hydrogenation catalyst with improved activity, and to the use of phenolic compounds for the activation of hydrogenation catalysts.
