Description of key information

Boiling: from ca. 212 °C at 1031 hPa to ca. 225 °C at 1040 hPa. Thermal decomposition in this temperature range is likely to occur.

Key value for chemical safety assessment

Additional information

In order to estimate the boiling point of the substance sulfuric acid, mono-C8-14 alkyl esters, ammonium salts, compds. with triethanolamine (CAS No. 96690-74-3), the results obtained experimentally for sulfuric acid, mono-C8-14 alkyl esters, ammonium salts (CAS No. 90583-10-1) and for sulfuric acid, mono-C8-14 alkyl esters, compound with triethanolamine (CAS No. 85665-45-8) are used in a weight of evidence approach. The two read-across substances can be seen as complementary to each other, providing both counter ions present in the target substance. As the measured boiling point values are to a good approximation similar, the range determined by them is acceptable as a boiling and/or decomposition range for the target. The lower of the two values is recommended to be used for a chemical safety assessment.

The experiments with both analogue substances were determined by Differential Scanning Calorimetry according to OECD Guideline 103.
