Results
Preliminary test (TGA)
From 175 °C upwards the weight of the sample decreased significantly. At 204 °C the sample weight had decreased by 25%. After the experiment it was observed that the test substance was evaporated from the sample container.
Main study (DSC)
DSC-curve of the first experiment:
An endothermic peak between 175 °C and 225 °C was observed. The extrapolated onset temperature of the peak was 191.95 °C. The effect was obtained due to boiling of the test substance. After the experiment it was observed that the test substance had evaporated from the sample container.
The second experiment was performed to obtain a duplicate value for the boiling temperature of the test substance. The temperature program was the same as during the first experiment.
DSC-curve of the second experiment:
The extrapolated onset of the evaporation peak was 191.85 °C. After the experiment it was observed that the test substance had evaporated from the sample container.
Description of key information
The boiling point of the test substance is 192 °C at 1009 +/- 2 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 192 °C
Additional information
The boiling point of the test substance was determined according to EU A.2 / OECD TG 103 by DSC (differential scanning calorimetry). The boiling point of the test substance is 192 °C at 1009 +/- 2 hPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
