Materials and methods
Test guidelineopen allclose all
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Guideline:
- other: OECD Guideline 104
- Principles of method if other than guideline:
- The determination of the Normal Boiling Temperature of a purified substance can be performed by dynamic vapour
pressure measurement according to the Annex to Commission Directive 92/69/EEC (A.2) and the OECD Test Guideline 103.
Therefore the Normal Boiling Temperature was deduced from vapour pressure data obtained by a dynamic method according
to the Annex to Commission Directive 92/69/EEC (A.4) and the OECD Test Guideline 104. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- dynamic method

Any other information on results incl. tables
DSC analysis: In order to survey the therrnic behaviour of the test item one determination (test1) was run up to 400°C. An exothermic decomposition was not observed. An endothermic peak with an onset at 344°C was observed. In combination with the recorded loss of mass this indicates the vaporization of the test item.
The regression of the results leads with a mean deviation of 0.09 % to the following equation: In(p/hPa) =17.3023 - 5344.17 /(170.49+ t/°C) The Normal Boiling Temperature was obtained by extrapolation. 344.3°C/1013.25hPa

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
