Reference
Preliminary test
Starting at 130°C, the weight of the sample decreased significantly. At 169°C, the sample weight had decreased by 25%. After the experiment it was observed that the test item was evaporated from the sample container.
Main study:
Experiment 1 - During cooling no effects were observed. During heating an endothermic peak was observed between 125°C and 200°C. The extrapolated onset temperature of the peak was 174.819°C. The endothermic effect was most likely obtained due to boiling of the test item. After the experiment it was observed that the test item had evaporated from the sample container.
Experiment 2 - In order to confirm whetherboiling caused the endothermicpeak, a higher heating rate of 50°C/minute was used. The extrapolated onset temperature was 175.465°C. The endothermic peak had not shifted to higher temperatures. It demonstrated that boiling of the test item caused the endothermic effect. After the experiment it was observed that the test item had evaporated from the sample container.
Experiment 3 - was performed as a duplicate of Experiment 1. Similar results as in Experiment 1 were obtained. The extrapolated onset of theboilingpeak was 174.965°C. After the experiment it was observed that the test item had evaporated from the sample container.
The boiling temperature was determined as the mean boiling temperature of Experiment 1 (174.819°C) and Experiment 3 (174.965°C).
Description of key information
Boiling point was determined by DSC. Boiling point of the test item was 174.9°C (448.0K). The boiling temperature was determined as the mean boiling temperature from two determinations - The boiling temperature was determined as the mean boiling temperature of Experiment 1 (174.819°C) and Experiment 3 (174.965°C).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 174.9 °C
