Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- ca. 80 °C
- Atm. press.:
- 1 013.3 hPa
Any other information on results incl. tables
A DSC-run in an aluminium crucible with a hole showed an exothermic effect (melting) in the temperature range of 55 -95 °C with an onset temperature of 76.5 °C. The melting point was determined with 76.4 °C.
In oder to clarify the results of the DSC measurement an additional with the capillary method was performed.
Set point: 40°C, heating rate 5 °C/min., end point 300 °C, melting range 80 - 82 °C.
75 °C: test item sinters
80 °C test item started to melt
82 °C melted, yellowish, unclear
121 °C clear, yellowish liquid
Due to this, it is concluded that the test item melted at app. 80 °C.
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.
