Results in detail
The melting temperature of the test item was found at -43 °C peak temperature (Determination A and B).
Determination |
peak temperature [°C] |
A |
-42.8 |
B |
-42.9 |
Mean value |
-43 |
Observed thermal processes
Cooled down from room temperature, the test item was amorphous with a glass transition at about-117 °C (Test 2). During the following heating, the test item crystallized. Therefore, to get a weil crystallized
test item, in the following measurements an additional annealing step at -60 °C was introduced.
After this, a rather sharp melting peak was found with a peak temperature of -43 °C and only a small rounding on the low temperature side due to impurities.
To survey the thermal behavior of the test item a preliminary TG/DSC-Test (non-GLP) was run up to 600 °C.
A distinct weight loss of more than 90 % at about 160 °Cis mainly caused by evaporation 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.
