Reference
Details:
The test item shows a melting area of crystalline subcomponents between -2 and +96 °C in the 1st heating run. The cooling run shows a crystallization. The 1st heating run shows a glass-transition temperature (of amorphous components) at ca. -30 °C, the 2nd heating run at ca. -27 °C.
Start of the area of melting temperature (defined by using the on-set temperature) from 3 independent single measurements:
0 °C (from first measurement)
-2 °C (from second measurement)
-3 °C (from third measurement)
Description of key information
-2 to 96 °C at ca. 1013 hPa (EU A.1)
Key value for chemical safety assessment
Additional information
The melting point of the substance was determined by Differential Scanning Calorimetry. The range of -2 to 96 °C represents a melting area of crystalline subcomponents. The heating runs showed a glass transition at ca. -30 °C. The cooling runs showed a cristallization.
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).
