Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The Henry’s law constant of C12-14 ADMAES was calculated to be 2.44 x 10-9 Pa-m3/mole at 25 °C.

Key value for chemical safety assessment

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

Additional information

The Henry’s law constant (HLC) of C12-14 ADMAES was estimated using the HENRYWIN v3.20 model. The method uses valid Bond contribution values, which are determined for 59 chemical bonds by a least-square analysis of HLCs for 345 organic compounds. The HLC was finally calculated on a weighted-average basis using the mole fractions of the individual components and was found to be 2.40 x 10-14 atm-m3/mole at 25°C (i.e., equivalent to 0.00000000244 Pa-m3/mole) (US EPA, 2012b), indicating the substance to be non-volatile.
