- 14 June 2016 to 04 October 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Remarks on result:
- other: self-reaction of components from approximately 118 °C (391 K) followed by partial boiling from approximately 227 °C (500K)
- Conclusions:
- The test item was determined to undergo self-reaction from approximately 118 °C (391 K) at 102 kPa followed by partial boiling (approximately 75%) from approximately 227 °C (500 K). As a result of the reaction, no value for the boiling point of the original components of the test item could be determined.

GUIDELINE
The determination was carried out by differential scanning calorimetry using a procedure designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
RESULTS
The test item was determined to undergo self-reaction from approximately 118 °C (391 K) at 102 kPa followed by partial boiling (approximately 75%) from approximately 227 °C (500 K). As a result of the reaction, no value for the boiling point of the original components of the test item could be determined.

RESULTS
- Thermograms for determinations 1 and 2 are shown in Figures 1 and 2 (attached).
- Thermographic data are summarised in Table 3 (below).
- After heating to 400 °C, the samples had lost approximately 73 % of their original weight.

Description of key information
An analogue test item was determined to undergo self-reaction from approximately 118 °C (391 K) at 102 kPa followed by partial boiling (approximately 75%) from approximately 227 °C (500 K). As a result of the reaction, no value for the boiling point of the original components of the test item could be determined (OECD 103 and EU Method A.2).
