Two measurements in aluminium crucibles with a hole showed an endothermic effect (boiling) in the temperature range 340 °C to 430 °C with an onset temperature between 366.0 °C and 366.6 °C.

Ident-No.	Onset / °C	Temperature range / °C	Crucible
32100	366.57	350 - 430	Aluminium with a hole
32101	365.98	340 - 430	Aluminium with a hole

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.

Ident.-No.	Onset / °C	Atmospheric pressure / hPa	Φ (group 2)	Δt / °C	Boiling point at 1013.3 hPa / °C
32100	366.57	1006	5.302	0.374	366.94
32101	365.98	1006	5.301	0.374	366.35

The test item has a boiling point at atmospheric pressure (1013.3 hPa) of 366.7 °C.

Conclusions:

The boiling point of the test substance was found to be 366.7 °C.

Executive summary:

A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two measurements with about 9 - 14 mg of the test item were performed. The crucible was heated from room temperature to 500 °C with 10 K/min heating rate. Two measurements in aluminium crucibles with a hole showed an endothermic effect (boiling) in the temperature range 340 °C to 430 °C with an onset temperature between 366.0 °C and 366.6 °C. The observed boiling point was corrected to atmospheric pressure. The test item has a boiling point at atmospheric pressure (1013.3 hPa) of 366.7 °C.
