Abstract
Official abstract text for this publication.
Processes for oxidizing an alkyl-aromatic compound are described. The processes include contacting an alkyl-aromatic compound, a solvent, a bromine source, a catalyst, and an oxidizing agent to produce a product comprising at least one of an aromatic alcohol, an aromatic aldehyde, an aromatic ketone, and an aromatic carboxylic acid. The composition of the solvent is controlled to reduce the impurities in the product.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for oxidizing an alkyl-aromatic compound comprising: contacting an alkyl-aromatic compound, a solvent, a bromine source, a catalyst, and an oxidizing agent to produce a product comprising terephthalic acid and wherein a CIELAB b* value of the terephthalic acid is less than about 5; wherein the solvent comprises a carboxylic acid and an ionic liquid and wherein the solvent has a ratio of the carboxylic acid to the ionic liquid within a range of…
