Description of key information
The melting point of TPP is 49.5 - 50 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 323 K
Additional information
Whilst the melting point values are reported within the range of 49 -52 °C. The publication by Dobry & Keller, where purification of TPP from methanol is specified, gives the narrow range of 49.5 -50 °C
