EC number: 442-730-6
CAS number: 35132-93-5
In both tests, an endothermal boiling peak was observed.
The measured temperatures are summarized in the following table.
Atmospheric pressure [mbar]
Amount of test substance [mg]
Start temperature [K / °C]
298 / 25
Heating rate [K/min]
[endothermal boiling] (K / °C)
382 / 109
Because the results are given without decimals, the atmospheric pressure
correction was not neccessary.
Summing up it can be said, that the test substance C-Quart has an exact
boiling point. The measured value is only valid for the available
concentration of the test substance. The boiling point stems from the
boiling of the water which is a major component (43%; m/m) of the test
substance. The precission of the DSC measurement is specified in the
guideline to be ± 0.5°C. This precission is only valid for pure test
substances but not for mixtures. Nevertheless it is added to the result
of this study.
The boiling point of the test item was determined by differential
scanning calorimetry in a GLP study according to EU test method A.2 and
OECD testing guideline 103. The boiling point of the test item is 109 °C.
The boiling point of the test item is 109 °C.
