Reference
Pre-test:
During cooling down, at 390 °C, cracked sound was observed. Because of safety reasons the test tube was taken out from the aluminium block. The test item showed decomposition, indicated by colour change (brown).
Siwoloboff method:
The determination of the main test of the boiling point following the SIWOLOBOFF method was performed in duplicate. In both determinations, decomposition was detected. The decomposition temperature was determined with 170.0 ± 0.0 °C (443.2 ± 0.0 K). This value is the mean of two independent determinations. The test item showed signs of decomposition during determination, indicated by colourchange and physical state change (polymerisation). Therefore, no boiling point could be determined.
Description of key information
The test was carried out following OECD test guideline 103. No boiling point could be determined as the test item started to decompose at a temperature of 170 °C.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
