Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Vapour pressure:  2.5 Pa at 20ºC 
Vapour pressure: 266.6 Pa and 267 Pa at 70ºC

Key value for chemical safety assessment

Vapour pressure:
266.6 Pa
at the temperature of:
70 °C

Additional information

The vapour pressure of cyanuric chloride stated in three different bibliographic sources is 266.6 and 267 Pa at 70ºC. In one of the publications, a 2.5 Pa value is stated at 20ºC. Attending to the reliability of the refereces, the 266.6 Pa (2 mm Hg) value has been proposed as the most accurate for vapour pressure at 70ºC.
