Abstract
Improvements in the object of the main patent no. 202.872 "by" process for the transformation by oxidation or p-xylol in derivatives of terephthalic acid "for the preparation of aromatic polycarboxylic acids by oxidation of alkylaromates with elemental oxygen or oxygen-containing gases in liquid phase optionally under pressure advantageously in the presence of catalysts with transposition of oxidation intermediates into oxidizable derivatives according to the main patent characterized in that relatively oxidisable oxidation intermediates are transposed which are presented in the oxidation of the alkylaromatos in functional derivatives more easily oxidizable and that they are subsequently oxidized by themselves or together with the starting hydrocarbons and/or with the mixture in which they have been present in the course of the oxidation.
