Additional information

The Henry’s law constant (HLC) of amides, C16-18 (even numbered) and C18-unsatd., N,N-bis(hydroxyethyl) was estimated by HENRYWIN v3.20 using bond contribution method. This 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 value of the HLC for amides, C16-18 (even numbered) and C18-unsatd., N,N-bis(hydroxyethyl) was finally calculated on a weighted-average basis using the mole fractions of the individual components.

 The estimated HLC value was found to be 9.2 x 10-12atm-m3/mole (9.32 x 10-7pa-m3/mole).
