Abstract
εραιτέρω διαμόρφωσις της μεθόδου προς παρασκευήν μονοεστέρων του βενζολοδικαρβονικού οξέος, ιδία των μονομεθυλεστέρων, δι' οξειδώσεως των εστέρων τουτολουϋλικού οξέος δια στοιχειακού οξυγόνου ή αερίων περιεχόντων οξυγόνον εις υψηλήν θερμοκρασίαν ενυγρά φάσει, ενδεχομένως υπό πίεσιν, επωφελώς παρουσία καταλυτών, ως αλάτων βαρέων μετάλλων, κατά τοδίπλωμα ευρεσιτεχνίας 14733 (Δήλωσις διπλώματος ευρεσιτεχνίας της 12.4.1951) εν τούτου διακρινομένη, ότι εστήρ του μ-τουλουϋλικού οξέος, ιδία ο μεθυλεστήρ, υποβάλλεται εις την οξείδωσιν. further formulation of the process for the preparation of benzedicarboxylic acid monoesters, monomethyl esters themselves, by oxidation of toluene acid esters with elemental oxygen or gases containing oxygen at high temperatures, 14733 (Patent Application of April 12, 1951) nevertheless disclosed that an ester of m-toluyl acid, methyl ester itself, is subjected to oxidation.
