Additional information

The boiling point of the substances of the Persulfate Category was determined according to EU method A.2 applying photocell detection. Diammonium-, -potassium- and -sodium persulfate were found to decompose at ca. 120 °C (393 K), 100 °C (373K) and 180 °C (453 K) at atmospheric pressures of about 1000 hPa before the boiling point was reached. Thus, for all three substances, no value for boiling temperature was determined.
