Type of information:

experimental study

Adequacy of study:

supporting study

Study period:

1 March 2013

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant result.

Qualifier:

according to guideline

Guideline:

OECD Guideline 103 (Boiling point/boiling range)

Deviations:

no

GLP compliance:

no

Type of method:

differential scanning calorimetry

Boiling pt.:

> 250 °C

Remarks on result:

other: No information on atm. pressure available.

No departure from the base line of the heat flow record was recorded throughout the full temperature range from 20 °C to 250 °C. The boiling point of the test material was therefore determined to be > 250 °C.

Conclusions:

Under the conditions of the study the boiling point of the test material was determined to be > 250 °C.

Executive summary:

The boiling point of the test material was determined in accordance with the standardised guideline OECD 103, by differential scanning calorimetry. No departure from the base line of the heat flow record was recorded throughout the full temperature range from 20 °C to 250 °C. The boiling point of the test material was therefore determined to be > 250 °C.

Table 1: Thermographic Data

Determination	Thermal Event	Interpretation	Temperature
			°C	K
1	Exotherm	Onset of decomposition	248.05	521.20
2	Exotherm	Onset of decomposition	252.50	525.65

Atmospheric pressure = 101.3 kPa

Conclusions:

Under the conditions of the study the test material was found to decompose from 248 °C at 101.3 kPa. As the test material decomposed, no value for boiling temperature could be determined.

Executive summary:

The boiling point of the test material was determined in accordance with standardised guidelines OECD 103 and EU Method A.2 using differential scanning calorimetry. Under the conditions of the study the test material was found to decompose from 248 °C at 101.3 kPa. As the test material decomposed, no value for boiling temperature could be determined.

Description of key information

Decomposition from 248 °C, OECD 103, EU Method A.2, Fox 2012

Additional information

In the key study (Fox, 2012), the boiling point of the test material was determined in accordance with standardised guidelines OECD 103 and EU Method A.2 using differential scanning calorimetry. Under the conditions of the study the test material was found to decompose from 248 °C at 101.3 kPa. As the test material decomposed, no value for boiling temperature could be determined. The study was conducted to GLP and was assigned a reliability score of 1 in accordance with the criteria of Klimisch (1997) and considered suitable as an accurate reflection of the test material.

 

Supporting information is available in the form of a study in which the boiling point of the test material was determined in accordance with the standardised guideline OECD 103, by diferential scanning calorimetry. No departure from the base line of the heat flow record was recorded throughout the full temperature range from 20 °C to 250 °C. The boiling point of the test material was therefore determined to be > 250 °C. The study was conducted to agreed protocols and was assigned a reliability score of 1 in accordance with the criteria of Klimisch (1997) and considered suitable as an accurate reflection of the test material.

Furthermore, a handbook abstract (Summer, 2003) with no reported methodology, reports the boiling point of the test material to be > 250 °C. Due to it not being possible to assess the accuracy of the information, the data was assigned a reliability score of 4 in accordance with the criteria of Klimisch (1997). The supporting data are in good agreement with findings of the key study.
