Description of key information
Experimental value of melting point: the test item didn't show a melting of crystalline subcomponents up to a temperature of 263 °C
Above 263 °C an exothermal effect was visible, probably due to evaporation or decomposition of the test item.
Transition temperatures were observed at 9 and 157°C (evaluated in the 2nd heating run). At these temperatures, the test item become more and more viscous but didn't melt.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 263 °C
Additional information
The determination of the melting temperature of the test item was performed by a Differential Scanning Calorimetry (DSC) analysis in accordance with the test method A.1. "Melting/Freezing Temperature" as described in the Official Journal of the European Communities L383A and GLP. No deviation from the guidelines was observed during the test.
Before the determination of the melting point of the test item, the hardware check of the DSC apparatus has been carried out with references substances (Water deionised, Alumel foil, Nickel foil, Indium and Tin). The results obtains were conclusive with the theoretical results so the apparatus was considered acceptable for use.
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.
