Abstract

έθοδος προς οξείδωσιν της π-ξυλόλης προς παράγωγατου τερεφθαλικού οξέος, εκ τούτου διακρινομένη, ότι οξειδούμεν την π-ξυλόλην δι' οξυγόνου ή αερίων περιεχόντων οξυγόνον, εις υψηλήν θερμοκρασίαν, ενδεχομένως υπό πίεσιν, επωφελώς παρουσία καταλυτών,εστεροποιούμεν, προσφόρως δια μεθανόλης, το σχηματισθέν μίγμα οξέων, το οποίον περιέχει ουσιώδεις ποσότητας τουλουϋλικού οξέος, ενδεχομένως μετ' αποχωρισμόν της αμεταβλήτου ξυλόλης, και οξειδούμεν περαιτέρω τον εστέρα δι' οξυγόνου ή αερίων περιεχόντωνοξυγόνον. Process for oxidizing p-xylol to a terephthalic acid derivative, therefore characterized by oxidizing p-xylene with oxygen or oxygen-containing gases, at high temperature, possibly under pressure, with the presence of a well-formed catalyst A mixture of acids containing a substantial amount of tuluary acid, possibly with the separation of the unchanged xylene, and further oxidizing the ester with oxygen or oxygen-containing gases.
