- Conclusions:
- The test item has been determined to decompose from approximately 200 °C (473 K) at 99 kPa. As the test item decomposed, no value for boiling temperature could be determined.
- Executive summary:
The boiling point of the test item was determined to a procedure compatible with EU Method A.2 and OECD Guideline 103 in compliance with GLP. Differntial scanning calorimetry was chosen as method. After being heated to 400°C, the residues had lost approximately 36 % and 42 % of their original weights.
As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated. As approximately 60% remained after heating to 400 °C, complete decomposition and volatilization of the test item had not occurred. The baseline shift between approximately 160 and 170 °C in Determination 1 was considered not to be a thermal event related to the test item. Thus, a third determination was performed to confirm this. Conclusively, the test item has been determined to decompose from approximately 200 °C (473 K) at 99 kPa. As the test item decomposed, no value for boiling temperature could be determined.
Reference
The thermograms and thermographic data for determinations 1 to 3 are shown in figures (see attachment) and table:
Thermal Event | Interpretation | Temperature [°C (K)] | ||
Determination 1 | Determination 2 | Determination 3 | ||
Exotherm | Onset of decomposition | 200.31 (473.46) | 206.88 (480.03) | 209.81 (482.96) |
Atmospheric pressure: 99 kPa
After being heated to 400 °C, the residues of the three determinations had lost approximately 36 % and 42 % of their original weight.
Overall result: decomposition from approximately 200 °C (473 K)
Discussion
As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated. As approximately 60% remained after heating to 400 °C, complete decomposition and volatilization of the test item had not occurred.
The baseline shift between approximately 160 and 170 °C in Determination 1 was considered not to be a thermal event related to the test item. Thus, a third determination was performed to confirm this.
Conclusion
The test item has been determined to decompose from approximately 200 °C (473 K) at 99 kPa. As the test item decomposed, no value for boiling temperature could be determined.
