Description of key information

The test substance dipotassium persulfate was determined to decompose at ca. 373 K (= 100 °C) at 100.66 kPa before the melting point was reached. Thus, no value for melting temperature was determined.

Key value for chemical safety assessment

Additional information

Following EU method A.1 (capillary method), the substances of the Persulfate Category were determined to decompose at approximately 120 °C (393 K), 100 °C (373K) and 180 °C (453 K) at atmospheric pressures of about 1000 hPa before the melting point was reached. Thus, for all three substances, no value for melting temperature was determined.
