p-Xylene Oxidation to Terephthalic Acid: New Trends

Hugo M. Lapa, Luísa M. D. R. S. Martins

Abstract

-xylene is an especially important process in the polyester industry, as it is mainly used in polyethylene terephthalate (PET) manufacturing, a polymer that is widely used in fibers, films, and plastic products. This review presents and discusses catalytic advances and new trends in terephthalic acid production (since 2014), innovations in terephthalic acid purification processes, and simulations of reactors and reaction mechanisms.
