Applicant's summary and conclusion

Conclusions:
The melting point of Triphenyl phosphite (TPPi) is approximately 25 °C (author). The reported melting point of TPPi on the CRC Handbook of Chemistry and Physics is approximately 25 °C (CRC 1975). This is an approximate melting point because TPPi does not give a sharp melting point due to its physical/chemical characteristics. The CRC reference is recognized by the US EPA as an acceptable source of physical/chemical parameters (US EPA, 1999).
