Pure Terephthalic Acid Preparation High temp.oxidation:While acetic acid as solvent,Co,Mn,Br admixture as catalyzer pne will oxidate into crude terephthalic acid<CTA>.Under certain temperature and pressure.Then CTA dissolve into water under
high temperature and pressure.And passa Pd/C catalyzer settled vessel which is a reactor where the oxidation production will be hydrogenated in order to removeimpurity(4-CBA).Afterward.the hydrogenation
production will become the final production(PTA) after crystallizing filtrating P-Tol acid and drying.
