Description of key information
Postassium cyanate decomposes at 700 - 900 °C. Determination of boiling point technically not feasible.
In addition, determination of boiling point is not required according to Annex VII REACH Regulation if melting point is above 300 °C.
Key value for chemical safety assessment
Additional information
Weight of evidence approach:
3 different handbooks show the same result for the determination of the boiling point, which is regarded as reliable. The substance decomposes at 700 - 900 °C. Determination of a boiling point is technically not feasible.
