Abstract: An aromatic dicarboxylic acid of chemical formula HOOC—Ar1—COOH is prepared in a process wherein a feedstock comprising at least an aromatic aldehyde compound of chemical formula (1): OHC—Ar1—COOH, wherein Ar1 represents an arylene or heteroarylene moiety, and an aqueous electrolyte are provided; the feedstock and the aqueous electrolyte are introduced into an electrolytic cell comprising electrodes, wherein at least one of the electrodes comprises a non-noble metal and/or an oxide and/or a hydroxide thereof and/or carbon; and the aromatic aldehyde compound of formula (1) is oxidized electrochemically to yield the aromatic dicarboxylic acid.

Abstract: A carboxylic acid-containing composition, which composition contains an aldehyde, is purified in a process, which process comprises introducing the carboxylic acid-containing composition and an aqueous electrolyte into an electrolytic cell comprising electrodes; electrochemically oxidizing the aldehyde in the electrolytic cell to obtain an electrochemically oxidized product composition comprising a carboxylic acid derived from the aldehyde; and, optionally, separating carboxylic acid from the electrochemically oxidized product composition.
