Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The melting point of diphenyl carbonate was addressed on a Weight of Evidence basis. The data available reported a range of values from 70 to 88 °C; the value of 78.8 °C (Buysch, 2002) was selected to be the key value for classification and risk assessment purposes as it is considered to be suitably representative.  

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
78.8 °C

Additional information

The melting point of diphenyl carbonate is considered to be 78.8 °C (at ambient pressure), based on a weight of evidence approach using five studies. 

 

All the data were from peer reviewed sources; therefore all were awarded a reliability score of 2 in accordance with the criteria for assessing data quality as set forth by Klimisch et al. (1997).

 

The first value is taken from Ullmann´s Encyclopaedia of Industrial Chemistry and identifies the melting point at 78.8 °C. 

The next value is taken from the Handbook Register in Beilstein. Several melting points in the range 70 to 88 °C are reported.

The third value is taken from the Merck Index. This identifies the melting point as 80 to 81 °C.

The fourth value is taken from the CRC Handbook of Chemistry and Physics, which identifies the melting point as 83 °C.

The final value is taken from Hawley’s Condensed Chemical Dictionary, which identifies the melting point as 78 °C.
