Beschreibung
Zusammenfassung:	A process is disclosed for liquid phase oxidation of alkyl aromatic hydrocarbons to aromatic carboxylic acids in presence of a multivalent catalyst promoted by a source of bromine. The oxidation is conducted in at least two oxidation reactions. Exothermic heat of reaction is controlled by means of a liquid phase heat exchanger to control temperature and pressure. Oxygen partial pressure in each stage is at least 1.5 psia to minimize oxygen starvation and improve selectivity. Low reactor temperature, high reactor pressure and improved selectivity improve product yield and product quality.
