Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Approximate accuracy of the instrument: ± 0.3 K (at 373 K) (bei photocell detection)

At small deviations from the normal pressure (max. ± 5 kPa) the boiling temperatures are normalized to Tn by means of the following number-value equation by Sidney Young:

Tn = T + ( fT x ∆p )

∆p = (101.325 – p)

p = pressure measurement in kPa

fT = rate of change of boiling temperature with pressure in K / kPa = 0.41

T = measured boiling temperature in K

Tn = boiling temperature corrected to normal pressure in K

Conclusions:
A boiling point of 206°C (479.2 K) at 1013 hPa was determined for the substance using a relevant test method. The result is considered to be reliable.

Description of key information

Boiling Point: 206°C at 1013 hPa (OECD 103)

Key value for chemical safety assessment

206 °C

Additional information

A measured boiling point of 206°C (479.2 K) at 1013 hPa was determined for the substance using a capillary tube (photocell detection) method in accordance with OECD Test Guideline 103 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.
