Check of the Apparatus
The apparatus was checkedwithcaffeineand ultra-pure water. The check of the apparatus showed that the instrument worked correctly and was fit for purpose.
Preliminary Test
The test item was put into the capillary tube, fused at one end, so that the filling level was approximately 5 to 10 mm. Then the filled capillary tube was placed in the metal heating block of the instrument. The test was started at 30 °C. The heating rate was 5 K/min.
A preliminary test was performed since no information of the expected boiling point was available.
The following observations were made:
At 256 °C: The test item formed bubbles.
At 260 °C: The test item began to change colour to dark-yellow .
As the test item started to decompose at 260 °C and no boiling point could be determined. Therefore no main test was performed.
Main Test
Preliminary testing showed that the test item decomposed during measurement and therefore no main test was performed.
Description of key information
The test was carried out following OECD guideline No. 103 and EC method A.2. No boiling point could be determined as test item started to decompose at a temperature of 260°C.
Key value for chemical safety assessment
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.
