Description of key information

The Henry’s law constant was calculated to be 1.02 x 10-11 atm-m3/mole at 25°C (i.e., equivalent to 0.00000104 Pa-m3/mole).

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0
at the temperature of:
25

Additional information

The Henry’s law constant (HLC) of C12-14 ADBAC was estimated with the HENRYWIN v3.20 model. The method used 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 1.02 x 10-11atm-m3/mole at 25°C (i.e., equivalent to 0.00000104 Pa-m3/mole) (US EPA, 2012). Based on this data, the substance is considered to be non-volatile.
