Description of key information

The vapour pressure of sodium cyanide is negligible at room temperature.

Key value for chemical safety assessment

Vapour pressure:
0.1 kPa
at the temperature of:
800 °C

Additional information

Temperatures must exceed 800 °C before measureable vapour pressure values are obtained. These range from 0.10 kPa at 800 °C to 39.10 kPa at 1360 °C.
