20 °C

Additional information

Henry’s Law Constant was calculated manually (Chemservice, 2014) and by the software tool EPIWIN/HENRYWIN v3.20 (Chemservice, 2014). The manual calculation according to ECHA REACH Guidance on information requirements and chemical safety assessment (Chapter R.16 - Environmental Exposure Estimation; version 2.1; October 2012) is considered as more reliable since substance specific properties (VP, WS) were taken into account. Conclusively, Henry's Law Constant amounts to 2.97 E-10 Pa*m3*mol-1at 20 °C.

The software tool HENRYWIN calculated a Henry´s Law Constant of 2.369 E-13 Pa*m3*mol-1 (25 °C) for the substance which is considered as supporting information. Both calculation methods determine a negligible Henry's Law Constant.
