Abstract

Abstract Aqueous sodium polysulfide of composition in the range Na 2 S 2.0 to Na 2 S 4.6 undergoes autoxidation by either air or pure oxygen at temperatures of between 23 and 40 °C according to the equation [xxx] Iodometric determination, vibrational spectra and ion-pair chromatography showed that neither sulfate, sulfite nor polythionates are formed and that the sulfur precipitated consists of S 8 (≥ 99%).
