摘要:A solid terephthalic acid composition and a process for producing terephthalicacid from para-xylene. The process comprises forming a mixture comprising the para-xylene, a solvent, a bromine source, and a catalyst; and oxidizing the para-xylene bycontacting the mixture with an oxidizing agent at oxidizing conditions to produce a solidoxidation product comprising terephthalic acid, para-toluic acid, 4-carboxybenzaldehyde.The solvent comprises a carboxylic acid having from 1 to 7 carbon atoms and an dialkylimidazolium ionic liquid; and the catalyst comprises at least one of cobalt, titanium,manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, andzirconium. The solid terephthalic acid composition comprises, less than about 4,000 ppm-wt 4-carboxybenzaldehyde content, and more than about 2,000 ppm-wt a para-toluicacid.
