Melting Point:
Conclusion: The available melting point data are adequate.
Basis for Conclusion: Melting point values within the range of 49-52°C are reported in a variety
of reputable secondary sources.

Boiling Point:
Conclusion: The available boiling point data are adequate.
Basis for Conclusion: Most sources report reduced-pressure boiling points of 244-245°C at 10
or 11 torr for triphenyl phosphate. Perry and Green (1984) report a boiling point of 413.5°C at
760 torr, which is consistent with the boiling point extrapolated using the Clausius-Clapeyron
Equation and the parameters measured by Dorby and Keller (1957). It has also been reported
that triphenyl phosphate decomposes at or near its boiling point (Dorby and Keller, 1957).
