    • 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.
    • 提供了对烷基取代的芳族化合物进行加氧的方法。 在此过程中,烷基取代的芳族化合物在合适的一元羧酸,至少部分可溶的Te或Se化合物,无机溴化合物和选自无机硝酸盐和可转化成无机硝酸盐的化合物的化合物存在下与分子氧接触 在该过程的条件下。 在本发明的一个实施方案中,该方法在两个不同的步骤中进行,其中烷基取代的芳族化合物和氧在必要组分存在下接触产生包含芳族醇和羧酸的酯,随后水解该 酯以产生具有羧酸再生的芳族醇。
