Applicant's summary and conclusion

Conclusions:

The boiling point of the aqueous solution was determined to be 108.4°C at 997 hPa. The boiling point of the concentrated material could not be measured due to its high viscosity. Therefore, the boiling point for the substance itself was estimated to b 415.15°C.

Executive summary:

The test was performed under GLP according to the Czechian testing method 1.4.4 (similar to method A.2 of Directive 67/548/EEC) in 2000. The calculation was done in 2011 using the EPI-Suite software v4.10.
