Atm. press.:
1 Bar
Decomposition:
yes
Decomp. temp.:
> 700 °C
Conclusions:
Sodium cyanate decomposes. Determination of boiling point technically not feasible.

Description of key information

Sodium cyanate decomposes to NaCN, Na2CO3, N2 and CO at a temperature over 700°C. Determination of boiling point technically not feasible. 

Key value for chemical safety assessment

Additional information

Weight of evidence approach:

2 different handbooks show the same value for boiling point (decomposition). This value is thus regarded as reliable.
