Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 197.1 °C
Additional information
A measured boiling temperature of 197.1°C (470.3 K) at 1013 hPa was determined for the submission substance using a photocell detection method in accordance with EU Test Method A.2 and in compliance with a known quality system (ISO 9001:2008). In addition to the photocell detection method, the boiling point of the substance was determined using a DSC method. A boiling point value of 195.9°C (uncorrected boiling temperature) was obtained for the substance. The results are considered to be reliable.
