PROCESS FOR OXIDATION OF ALKYL AROMATIC COMPOUND TO AROMATIC CARBOXYLIC ACID

摘要

The present disclosure provides a process for oxidation of p-xylene to terephthalic acid. Recovery of fluid medium and valuable chemicals is carried out using p-xylene as fluid medium which is also the starting material. The recovered stream containing p-xylene, acetic acid and other valuable chemicals is recycled to the oxidation step. The process disclosed in the present disclosure is energy efficient and cost effective.
