- Atm. press.:
- 971.8 hPa
- Decomposition:
- yes
- Decomp. temp.:
- > 333 - <= 335 °C
- Sublimation:
- no
- Remarks on result:
- other: Melting point could not be determined since the test item started decomposing at 333 °C - 335 °C with colour change from red to black
- Conclusions:
- The melting point determination of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1) was done following OECD Guideline 102 and according to the metal block capillary method. The test item started decomposing at 333°C and completes at 335°C with colour change from red to black. The decomposition range was observed to be 333°C-335°C at 971.8 hPa.
- Executive summary:
The melting point determination of Test item Dialuminium tris[2 -(2,4,5,7 -tetrabromo-6 -oxido-3 -oxoxanthen-9 -yl)-3,4,5,6 -tetrachlorobenzoate] (CAS No. 15876 -58 -1) was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test item started decomposing at 333°C and completes at 335°C with colour change from red to black. The decomposition range was observed to be 333°C-335°C at 971.8 hPa.
