PROCESS FOR THE HYDROGENATION OF ALKYLARYL KETONES

摘要

The invention relates to a process for the hydrogenation of an alkylaryl ketone which process comprises contacting a feed containing an alkylaryl ketone with hydrogen in trickle-flow mode in the presence of a heterogeneous hydrogenation catalyst, in which process the dynamic liquid hold-up is of from 10 to less than 30% and the external area of the catalyst particles is effectively wetted by the liquid flowing down.
