- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- January 20, 2016 - March 11, 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- > 160 °C
- Atm. press.:
- ca. 765.3 mm Hg
- Decomposition:
- yes
- Remarks:
- The test material turned black
- Decomp. temp.:
- ca. 350 °C
- Remarks on result:
- not determinable
- Remarks:
- The testing was discontinued at that point due to lack of bubble visibility.
- Conclusions:
- It was not possible to determine the boiling point of the registered substance as it decomposed at temperatures above 350°C without boiling.
- Executive summary:
The study was performed based on procedures in the U.S. EPA Product Properties Test Guidelines, OPPTS 830.7200,Melting Point/Melting Range(1); OECD Guideline for the Testing of Chemicals, 102,Melting Point/Melting Range(2); U.S. EPA Product Properties Test Guidelines, OPPTS 830.7220,Boiling Point/Boiling Range(3); and OECD Guideline for the Testing of Chemicals, 103,Boiling Point(4). The experimental portion of the study was conducted between January 20 and 21, 2016.
During the definitive boiling point testing the test substance samples provided the first bubble observations at approximately 160°C. Although the test material did produce bubbling throughout the testing period, the bubble production frequency was not such that an actual definitive boiling point/range could be made. The test material turned black at a temperature of approximately 350°C. The testing was discontinued at that point due to lack of bubble visibility.

- Appearance: Light brown solid
Storage conditions: Room temperature in the dark
Expiry date: September 2004 - Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 230 °C
- Conclusions:
- The boiling temperature of the test substance was not determinable, as the test material decomposed at temperatures above 230°C without boiling.
- Executive summary:
The boiling temperature was examined by a modified Siwoloboff method.
A boiling tube (3.2 mm diameter) was filled to a height of 5 - 10 mm with the sample and a boiling capillary was immersed, open end first.
The boiling tube containing the sample and the boiling capillary was inserted into the sample holder and observations recorded as the temperature was raised.
The results of the boiling point determinations on the test substance were as follows: Barometric pressure: 1011 mbar.
As the temperature increased, the samples were observed to darken significantly above approximately 230°C, indicating decomposition. No sign of boiling was noted.
The boiling temperature of the test substance was not determinable, as the test material decomposed at temperatures above 230°C without boiling.

During the definitive boiling point testing the test substance samples provided the first bubble observations at approximately 160°C. Although the test material did produce bubbling throughout the testing period, the bubble production frequency was not such that an actual definitive boiling point/range could be made. The test material turned black at a temperature of approximately 350°C. The testing was discontinued at that point due to lack of bubble visibility. Results of the uncorrected boiling point determinations for the test substance are presented in Table 3.

Description of key information
Two studies were performed on the registered substance. The boiling point could not be determined as the substance decomposed.
Key value for chemical safety assessment
Additional information
The study was performed on the registered substance. The boiling point of the test substance was to be evaluated in accordance with the OECD Guideline for Testing of Chemicals 103 using a modified Siwoloboff method.
During the definitive boiling point testing the test substance samples provided the first bubble observations at approximately 160°C. Although the test material did produce bubbling throughout the testing period, the bubble production frequency was not such that an actual definitive boiling point/range could be made. The test material turned black at a temperature of approximately 350°C. The testing was discontinued at that point due to lack of bubble visibility.
