Description of key information

The key value for chemical safety assessment is taken from a calculation according to the Bond Method. Another result is given, calculated using the Group Method; H = 2.54E-5 Pa-m³/mole (Chemservice S.A., 2010).

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
25 °C

Additional information

Concerning the calculated results of the computer program EPIWIN by Chemservice S.A. (2010) as well as the estimated value of the peer-reviewed database HSDB (2010), which gives a value of 0.00000011 atm-cu/mol for the substance specific Henry´s Law Constant it can be hypothesized that N-Methylethanolamine will not evaporate from the water surface into the atmosphere.
