Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
2009-10-9 to 2009-11-19
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
other: OECD 104
Deviations:
no
Principles of method if other than guideline:
The test item is a mixture of substances of different volatility, in
consequence the dynamic method according to OECD
Guideline for the Testing of Chemicals 103 is not suitable.
GLP compliance:
yes (incl. QA statement)
Remarks:
BASF SE, GKA Kompetenzzentrum Analytik, 67056 Ludwigshafen, Germany.
Type of method:
other: static method
Specific details on test material used for the study:
Puity. 94.1 g/100 g by 1H-NMR spectroscopy with internal standard, determined during the GLP-study No. 09L00333 from GKA Competence Center Analytics, BASF SE
Key result
Atm. press.:
1 013.25 hPa
Decomposition:
yes
Decomp. temp.:
> 120 °C

At a temperature of 120°C, a continuously decreasing vapour pressure was observed, caused by a limited stability and a thermal change of the test item. Therefore, the boiling point of the test item cannot be determined.

Description of key information

The substance decomposes before boiling.

Key value for chemical safety assessment

Additional information

A GLP study was conducted (BASF, 09L00334, 2009) to determine the vapour pressure of the test item. Due to the different volatilities of the constituents the dynamic method according to OECD Guideline for the Testing of Chemicals 103 is not suitable. Therefore the determination of the boiling point was carried out via vapour pressure measurement by the static method according to OECD Guideline for the Testing of Chemicals 104. At a temperature of 120 °C, a continuously decreasing vapour pressure was observed, caused by a limited stability and a thermal change of the test item. Therefore, the boiling point of the test item cannot be determined. It was concluded that the substance decompose before boiling.
