Description of key information
A weight of evidence approach identified the boiling point for 2,6-xylenol as 46 °C (mean value).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 202 °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 81st edition of the CRC Handbook of Chemistry and Physics, which identifies the boiling point as 201.0 °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 was taken from the eighth edition of the Sax’s Dangerous Properties Handbook, which identifies the boiling point as 203 °C. As this is data from a non-peer reviewed source, it was awarded a reliability score of 4 in accordance with the criteria for assessing data quality as set forth by Klimisch et al. (1997).
The third value was taken from the fourth edition of the Verschueren Handbook of Environmental Data on Organic Chemicals, which identifies the boiling point as 203 °C. As this is data from a non-peer reviewed source, it was awarded a reliability score of 4.
The fourth value is taken from the second edition of the Kirk-Othmer Encyclopedia of Chemical Technology, which identifies the boiling point as 203 °C at 101.3 kPa. As this is data from a peer reviewed source, it was awarded a reliability score of 2
The fifth value was taken from the eleventh edition of the Merck Index, which identifies the boiling point as 201.03 °C. As this is data from a peer reviewed source, it was awarded a reliability score of 2
The final value was taken from a publication in the J. Chem. Soc. The boiling point was reported as 201.030 °C at 760 mm. Hg. As the method was not described, it was awarded a reliability score of 4.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
