Abstract
A találmány tárgya eljárás 97%-os tisztaságú, disav-szubsztituáltaromás előállítására, amely eljárás során: betáplálási áramotbiztosítanak, amely dialkil-szubsztituált aromást és szerves savoldószert tartalmaz; a betáplálási áramot egy gőzárammalérintkeztetik, a gőzáram legalább 50 térfogat% oxigént tartalmaz, ésaz oxigén parciális nyomása legalább 0,07 bar, 80-130 °Chőmérsékleten, egy katalizátorrendszer jelenlétében, amely cirkóniumotés kobaltot tartalmaz, ahol a kobaltnak a cirkóniumhoz viszonyítottmólaránya (5:1 ) - (15:1) és az érintkeztetést kevert üstreaktorbanvégzik; a kevert üstreaktorból egy gőzáramot távolítanak el, amelyszerves savat és vizet tartalmaz; a szerves sav és a víz legalább egyrészét kondenzáltatják a gőzáramból; a gőzáramból elválasztott szervessavból a víz legalább egy részét elválasztják; a kondenzált szervessav legalább egy részét visszavezetik a kevert üstreaktorba; a kevertüstreaktorból folyamatosan eltávolítják a reaktorterméket, amelydisav-szubsztituált aromást tartalmaz; a reaktortermékből elválasztjáka disav-szubsztituált aromás szilárd kristályait; és a disav-szubsztituált aromás szilárd kristályaiból kinyerik a legalább 97tömeg%-os tisztaságú disav-szubsztituált aromást. A nagy tisztaságútermék mellett a találmány szerinti eljárás további előnye, hogykivitelezése egyszerű rozsdamentes acél reaktorban történhet, és arefluxáltatásos hűtés következtében a reaktor eltömődése nemkövetkezik be.
