Information
Guideline(s) Result Comment Melting temperature EC A.1 -26.8°C (246.3K) differential scanning calorimetry (DSC) glass transition OECD 102 OPPTS 830.7200
Reference
The DSC curve obtained with Experiment 1 is shown in Figure 2. During cooling a glass transition was observed between -20°C and -60°C followed by an effect between -60°C and -80°C. The effect was obtained by an artefact (results are archived in the raw data).
Experiment 2 was performed to reconfirm the results of the glass transition temperature from Experiment 1. Figure 3 shows the DSC curve obtained. Similar results as in Experiment 1 were obtained. The inflection point temperature was -26.958°C. After the experiment the residue remained in the sample container was unchanged.
The glass transition temperature was determined as the mean inflection point temperature of Experiment 1 (-26.712°C) and Experiment 2 (-26.958°C).
Description of key information
Study conducted to recognised testing guidelines with GLP certification.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -26.8 °C
Additional information
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.
