ABSTRACT:
A process is provided for oxygenating alkyl-substituted aromatic compounds. In the process alkyl-substituted aromatic compounds are contacted with molecular oxygen in the presence of a suitable monocarboxylic acid, an at least partially soluble Te or Se compound, an inorganic bromine compound, and a compound selected from inorganic nitrates and compounds convertible to inorganic nitrates at conditions of the process. In an embodiment of the invention the process is carried out in two distinct steps with contact of the alkyl-substituted aromatic compounds and oxygen in the presence of the essential components produce an ester comprising both an aromatic alcohol and the carboxylic acid with subsequent hydrolyzing of this ester to produce an aromatic alcohol with regeneration of the carboxylic acid.
