Applicant's summary and conclusion
- Conclusions:
- The test item has no boiling point at atmospheric pressure up to its decomposition starting at ca. 290°C.
- Executive summary:
The boiling point of the test item was investigated in a study conducted according to OECD Guideline 103 (Boiling Point; 1995) and EU Method A.2 (Boiling Temperature; 2008) using DSC measurements. The results obtained were verified via the capillary method. The DSC measurements indicated exothermic effects between 290 and 360°C as well as between 370 and 500°C. The test item showed no boiling point at atmospheric pressure up to the decomposition temperature of ca. 290°C. During the measurements via the capillary method, the test item became light yellow at ca. 240°C, brown at ca. 255°C, and at 269°C the test item started to climb up the capillary. At ca. 277°C the test item and its decomposition products were no longer visible. No boiling of the test item could be observed at atmospheric pressure.
