Beschreibung
Zusammenfassung:	Disclosed is a process for synthesizing aromatic acids and diacids which comprises reacting aromatic hydrocarbons with a carboxyl source selected fro m 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 thei r structure.
