- Executive summary:
Introduction
The melting/freezing point of the test substances was determined using a method designed to meet the requirements of the following guidelines:
- Method A.1 Melting/Freezing Temperature and A.2 Boiling Temperature of Commission Regulation (EC) No. 440/2008 of 30 May 2008
- Methods 102 and 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Method
The determination was carried out by differential scanning calorimetry using a Mettler Toledo DSC822e Differential Scanning Calorimeter (DSC) incorporating a ThermoHaake Cooler EK45/MT. The tests were performed in air and nitrogen atmospheres.
The temperature accuracy of the DSC was checked prior to testing with indium and zinc. Aliquots of test item were placed in crucibles and were subjected to individual thermal programs.
Results and Conclusion
The test item was determined to decompose from approximately 130 °C (403 K), at 100.4 to 102.2 kPa. As the test item decomposed, no value for melting point could be determined.
Reference
Based on the thermographic profiles obtained using air and nitrogen atmospheres the indication is that the decomposition is probably thermal and not oxidative.

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).
