Description of key information

Three values were available for assessment, all reported at reduced pressures.

180 °C at 2 mm Hg (reported in 2 of the data sources)

210-214 °C at 10 mm Hg

254 °C at 50 mm Hg

Rationale for the use of reduced pressures was not provided.

Key value for chemical safety assessment

Additional information

A weight of evidence approach was taken when assessing the boiling point of the substance. The data used to fulfil this data requirement were all sourced from the following peer reviewed handbooks:

 

Lewis, RJ (2002), Hawley's Condensed Chemical Dictionary, 14th Edition

Verschueren, K (2001) Handbook of Environmental Data on Organic Chemicals (4th Edition)

Gangolli, S. ed. (2005) Dictionary of Substances and Their Effects (DOSE, 3rd Electronic Edition)

Prager, JC (1998) Environmental Contaminant Reference Databook, Volumes 1-3

 

All were assigned a reliability score of 2.
