See endpoint 4.2 (melting temperature). Boiling of the test substance was not observed below the temperature at which decomposition started.
Description of key information
No boiling of OS2600 was observed below the decomposition temperature of 150°C. The boiling point of MPKO, the main hydrolysis product of OS2600 was determined to be 172°C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 172 °C
Additional information
Key study: The boiling point test was performed on OS-1600 in accordance with OECD Guideline 103 and EU Method A.2. In a differential scanning calorimetry study, the substance has no boiling temperature. It decomposes at > 150°C.
Supporting study: The boiling temperature of the analogue substance MPKO was determined using a Q100 difference scanning calorimeter. The boiling point was 172°C at an atmospheric pressure of ca. 101.7 kPa.
