- 250 °C
- Conclusions:
- Diammonium hexachloropalladate has been determined to decompose from 250 °C
- Executive summary:
This is a GLP compliant, guideline study which is considered suitable for use as the key study for this endpoint. Diammonium hexachloropalladate has been determined to decompose from 250 °C.
Reference
Diammonium hexachloropalladate has been determined to decompose from 250 °C (523K). Similar thermographic profiles were obtained using air and nitrogen atmospheres, this indicates that the observed decomposition in both determinations is probably thermal and not oxidative. There were no signs of melting in determinations 1 and 2, however the test item had changed colour from a brown/red powder to a grey powder. In determination 3 the test item was heated to 250 °C after which the test item appearance was a red powder.
Description of key information
Diammonium hexachloropalladate has been determined to decompose from 250 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 250 °C
Additional information
The result is taken from a GLP-compliant, guideline study which is considered suitable for use as the key study for this endpoint (Tremain and Atwal 2011). Diammonium hexachloropalladate has been determined to decompose from 250 °C.
