For the correction Δt of the boiling point to standard atmospheric pressure (1013.3 hPa) the equation, table and graphs of H.B. Hass and R.F. Newton in „CRC Handbook of Chemistry and Physics, 74th ed. 1993-1994", pages 15-16 and 15-17 were used.

 

Δt = [(273.15+t) (3.0057-log p)] / [Φ+ 0.15(3.0057-log p)]   (t in °C, p in hPa)

For the estimation of Φ the test item was classified in group 2 (hydrocarbons) according to the table of H.B Hass and R.F. Newton.

The boiling range of the test item at atmospheric pressure (1013.3 hPa) is 365 - 369 °C.

Conclusions:
The boiling point of the test item was between 365 and 369 °C.
Executive summary:

A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry (DSC). The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Three measurements in aluminium crucibles with a hole showed an endothermic effect after the melting in the temperature range of 330 - 380 °C with an onset temperature of approximately 365 °C was determined. The boiling point of the test item was between 365 and 369 °C.

Description of key information

The boiling point of the test item was between 365 and 369 °C.
