摘要:
In a process for recovering terephthalic acid from its salts solution an aqueous solution of a terephthalic acid salt is fed into a cathode compartment of an electro dialysis cell and an electrolyte to an anode compartment, the resulting salt and electrolyte solution is then subjected to electrolysis and terephthalic acid resulting from the reaction of terephthalic acid anions with the electrolyte cations in the anode compartment is withdrawn from the anode compartment and separated from the electrolyte by filtration.
