Description of key information
The boiling point of methacrylamide is reported to be 225 °C at 1013 hPa (SIDS). This value is supported by a calculation with MPBPWIN (BP calculated: 210 °C).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 225 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
