Preliminary Test
Starting at 100°C, the weight of the sample decreased significantly. At 142°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
In a first experiment, an endothermic peak was observed between -25°C and 25°C during heating. The extrapolated onset temperature of the peak was -4.066°C. The endothermic effect was due to melting of the test item. Another endothermic peak was observed between 100°C and 175°C. The extrapolated onset temperature of the peak was 150.826°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.
In order to investigate the boiling peak, a higher heating rate of 50°C/minute was used in a second experiment. The extrapolated onset temperature was 151.113°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.
A third experiment was performed as a duplicate of the first experiment. Similar results as in the first experiment were obtained. The extrapolated onset of the boiling peak was 150.054°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 the first experiment (150.826°C) and third experiment (150.054°C).
The boiling point for the test substance was reported to be 150°C in a recognized database : PHYSPROP (part of EPISuite QSAR).
No atmospheric pressure was indicated for the boiling point value. It is assumed that this parameter was determined at normal atmospheric pressure
The boiling point for the test substance was stated to be 145°C.
No atmospheric pressure was indicated for the boiling point value. It is assumed that this parameter was determined at normal atmospheric pressure
The boiling point for the test substance was reported to be 150°C in a literature source. This data was obtained by calculation using "Electropological state indices".
No atmospheric pressure was indicated for the boiling point value. It is assumed that this parameter was determined at normal atmospheric pressure
The boiling point for the test substance was reported to be 150°C in four different literature sources cited in the same public database.
No atmospheric pressure was indicated for the boiling point value. It is assumed that this parameter was determined at normal atmospheric pressure
Description of key information
The boiling point of the test item was investigated in a GLP-compliant study performed in accordance with EC A.2 Method and OECD Guideline No. 103, using Differential Scanning Calorimetry (DSC). The boiling temperature of the test item was 150.4°C (423.6K). This experimental value is further supported by data from the literature.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:

Additional information
The boiling point of the test item was investigated in a GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint. Literature data are also reported for the endpoint and selected as supporting studies (Klimisch 2 or 4).
