Reference
Preliminary test
From approximately 250 °C upwards the weight of the sample decreased significantly. At 310 °C, the sample weight had decreased by 25%. After the experiment, there appeared to be no test substance remaining in the sample pan.
Main study
First experiment
During cooling an exothermic peak was observed between -30 °C and -40 °C indicating crystallization of the test substance. During heating from -90 °C to 241 °C a glass transition and exothermic crystallization peak were observed between -25 °C and 0 °C. An endothermic peak was observed between 0 °C and 50 °C. Melting of the test substance probably caused this effect. The extrapolated onset temperature of this peak was determined to be 14 °C. However, since the exothermic and endothermic effects observed between -25 °C and 50 °C were poorly resolved, the onset temperature of the melting peak could not be determined properly and will therefore not be considered for the calculation of the melting temperature.
Second experiment
During cooling an exothermic peak was observed between -20 °C and -30 °C indicating crystallization of the test substance. During heating from -90 °C to 400 °C a glass transition and exothermic crystallization peak were observed. Between 0 °C and 50 °C an endothermic peak was observed which was well separated from the exothermic peak at approximately 0 °C. Melting of the test substance caused this effect. The extrapolated onset temperature of this peak was determined to be 14 °C. Another endothermic peak was observed between 300 °C and 375 °C. Boiling of the test substance caused this effect. The extrapolated onset temperature of this peak was determined to be 343°C.
Third experiment
The same observations were made as during the second experiment. The extrapolated onset temperature of the melting peak was determined to be 14 °C. The extrapolated onset temperature of the boiling peak was determined to be 342 °C.
Fourth experiment
In order to confirm boiling of the test substance at approximately 342 °C, the fourth experiment was conducted using a closed sample container.During heating from-90 °C to 400 °C, an endothermic peak was observed starting slowly at approximately 325°C and being pronounced from about 375°C on. Since the endothermic effect shifted towards higher temperatures under these experimental conditions, it was confirmed that the observed effect was due to boiling of the test substance.
Conclusion
A boiling point of 342 °C for the test item was determined according to OECD Guideline 103.
The atmospheric pressure during the performance of the tests was 101.4 kPa.
Description of key information
