Description of key information

In accordance with section 7.12 of Column 2 of Annex VII, the study does not need to be conducted for solids with a melting point ≤ 160 °C. As the melting point of 2,6-Xylenol is 46 °C, it is considered justified to omit this study and the substance is not considered to be sensitive to self-ignition. 

Key value for chemical safety assessment

Additional information

Supporting information is also provided to address this endpoint. Two sources of data were available; these are experimental values reported in formats which have been peer reviewed. Both 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 experimental value reported was obtained from the Physical and Thermodynamic Properties of Pure Chemicals - Data Compilation and Hazardous Chemicals Data Book. The auto-ignition temperature of 2,6-xylenol was concluded to be 872.04 K.

 

The second value was cited in Japan’s National Institute of Technology and Evaluation database and the Handbook of Chemical Compound Data for Process Safety. The autoignition temperature of 2,6-xylenol was determined to be 1110 °F.
