- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- In accordance with REACh Regulation Annex VII, a study for determination of the vapour pressure need not be to conducted if the melting point is above 300 °C. Potassium cyanate has a melting point of 315 °C.
For potassium cyanate the vapour pressure was calculated to be 2.91 E-7 Pa at 25 °C. - Executive summary:

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
