Observed thermic processes:
In the first heating, the melting range extends from about 60°C up to 122°C with a maximum at 11 0°C. After slowly cooling down with 2 Klmin, the upper end of the melting range was lowered about 8K to 114°C. lt demonstrates a large influence of the thermal history on the position of the melting range.
To survey the thermic behaviour of the test item, a TG/DTA test (non-GLP) was run up to 700°C. Starting at about 160°C the weight loss of about 100% shows the vaporization I decomposition of the test item.
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.
