Hydrogenation of aromatic compounds to the corresponding cycloaliphatic comprises feeding reactants over fixed catalyst and removal of cycloaliphatic from side take off and/or column sump

摘要

Hydrogenation of a mono- or multi-nuclear aromatic, optionally substituted by an alkyl, amine and/or hydroxy group, to the corresponding cycloaliphatic with gaseous hydrogen in the presence of at least one catalyst in a reactor column comprises feeding the reactants over the fixed catalyst in the column such that the cycloaliphatic is removed via side take off and/or sump of column.
