- Executive summary:
The boiling point of TPP is estimated to be 414 °C at 760 Torr.
Reference
The result for the boiling point is an extrapolation - the decomposition temperature is a measured result
Description of key information
The boiling point at atmospheric pressure (760 torr/mmHg) is 413.5-414 °C
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 687 K
Additional information
Most sources report reduced pressure boiling points of, for example, 244 -245 °C at 10 or 11 Torr. A boiling point of 413.5 °C has been reported by Perry & Green (1984) which agrees with the boiling point extrapolated using the Clausius-Clapeyron equation and the parameters measured by Dobry & Keller (1957). It has also been reported that TPP decomposes at or near its boiling point (Dobry & Keller (1957).
