Beschreibung
Zusammenfassung:	Disclosed is a process for synthesizing aromatic acids and diacids which comprises reacting aromatic hydrocarbons with a carboxyl source selected from basic carbonate containing salts and carbon dioxide at elevated temperature under conditions in which said carboxyl source exhibits sufficient mobility to effect a net reaction to form aromatic acid salts, and aromatic polyacid salts, incorporating the aromatic hydrocarbon used in the reaction into their structure. Cette invention concerne un procédé de synthétisation d'acides et de diacides aromatiques consistant à faire réagir des hydrocarbures aromatiques avec une source de carboxyle prise dans des sels contenant du carbonate basique renfermant des sels et un dioxyde de carbone à une température élevée et dans des conditions telles que ladite source de carboxyle présente une mobilité suffisante pour déclencher une réaction nette donnant des sels acides aromatiques et des sels polyacides aromatiques en intégrant dans leur structure les hydrocarbures aromatiques utilisés dans la réaction.
