Description of key information

A weight of evidence approach identified the melting point for 2,6-xylenol as 46 °C (mean value).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
46 °C

Additional information

This endpoint is addressed on a weight of evidence basis. Six pieces of data are provided.

The first value is taken from the second edition of the Kirk-Othmer Encyclopedia of Chemical Technology and identifies the melting point as 48.0 °C. As this is data from a peer reviewed source, it was awarded a reliability score of 2 in accordance with the criteria for assessing data quality as set forth by Klimisch et al. (1997).

 

The second value is taken from a publication in the J. Chem. Soc. In the reported study, which was performed according to scientific methods, the freezing point is reported as 45.56 °C. As this is data from a peer reviewed source, it was also awarded a reliability score of 2.

 

The third value is taken from the eighth edition of the Sax’s Dangerous Properties Handbook. This identifies the melting point as 48-49 °C. As this is data from a non-peer reviewed source, it was awarded a reliability score of 4.

 

The fourth value was taken from the eleventh edition of the Merck Index, which identifies the melting point as 45.62 °C. As this is data from a peer reviewed source, it was awarded a reliability score of 2.

 

The fifth value is taken from the CRC Handbook of Chemistry and Physics, which identifies the melting point as 45.7 °C. As this is data from a peer reviewed source, it was awarded a reliability score of 2.

 

The final value is taken from the fourth edition of the Verschueren Handbook of Environmental Data on Organic Chemicals which identifies the melting point as 44-46 °C. As this is data from a non-peer reviewed source, it was awarded a reliability score of 4.
