Reference
Endpoint:
boiling point
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Data fron peer reviewed journal (referred to in TPP Hazard Review, US EPA, 29th August 2005)
Qualifier:
no guideline followed
Principles of method if other than guideline:
Extrapolated according to the Clausius-Clapeyron equation using experimentally derived parameters
GLP compliance:
not specified
Type of method:
other: Calculation
Specific details on test material used for the study:
Purified by recrystallisation from methanol
Boiling pt.:
414 °C
Atm. press.:
760 Torr
Decomposition:
yes
Remarks:
Measured experimentally
Decomp. temp.:
> 410 °C

The result for the boiling point is an extrapolation - the decomposition temperature is a measured result

Conclusions:
The boiling point of TPP is estimated to be 414 °C at 760 Torr.
Executive summary:

The boiling point of TPP is estimated to be 414 °C at 760 Torr.

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).
