Processes have been developed to obtain recycle ionic liquid streams which are active for oxidation of alkyl aromatic compounds, and which reduce the amount of 4-CBA in the solid oxidation products. The process can reduce the makeup amount of ionic liquid, carboxylic acid, catalyst, bromine source, and ammonia source.
