Description of key information

The boiling point as determined by the Siwiloboff method was 118C. However, this does seem quite low and may be a reflection of the water of crystallisation content rather than the underlying boiling point of the anhydrous material. The test item is believed to decompose above 200°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
118 °C
