Zusammenfassung:	A process for recovery of valuable materials from terephthalic acid manufacture. The process comprises the steps of diluting the reactor effluent from terephthalic acid manufacture with water in the weight ratio 1:1 to 1:12 and chilling the dilution of the effluent to 5 to 20 °C under stirring. The aqueous phase rich in the spent oxidation catalyst is separated from the solid phase rich in organic compounds and concentrated to recover the spent oxidation catalyst and water. Also equipment for recovery of valuable materials from the reactor effluent.
