Description of key information

The Henry's Law Constant of Diurea 8 was determined to range from 1.35E-13 to 3.91E-11 Pa-m3/mol using the bond estimation method and from 9.39E-6 to 1.04E-2 Pa-m3/mol using the group contribution method.

Key value for chemical safety assessment

Additional information

The Henry's Law Constant of Diurea 8 was estimated using the bond estimation and group contribution methods of HENRYWIN v3.20 (US EPA 2009). The vapour pressure of Diurea 8 is less than 10 E-10 Pa and it is expected that the substance would not enter the atmosphere. Therefore volatilisation is not considered to be a relevant environmental transport process for Diurea 8.
