Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect in the temperature range of 220- 285 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline.

No further endothermal or exothermal effects were observed up to the final temperature (500 °C). The mass loss after the DSC measurements amounted to 100 %. The results of the DSC measurements are summarized in the Table below:

Ident No.	Test item / mg	Starting temp / °C	Final test temp / °C	Temp. range (endothermal) / °C	Onset (boiling) /°C	Crucible	Observations after the measurement
39043	12.85	25	500	200 - 285	264.21	Aluminium with a hole	Mass loss: 100 %
39044	12.42	25	500	230 - 285	264.01	Aluminium with a hole	Mass loss: 100 %

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- logp))
t Temperature in °C
p pressure in hPa

For the estimation of φ the test item was classified in group 3 (amines) according to the table of H.B Hass and R.F. Newton in “CRC Handbook of Chemistry and Physics", (Figure 3 on page 14).

The results are shown in the Table below.

Ident No.	Onset / °C	Ambient pressure / hPa	φ (Group 3)	Δt / °C	Boiling point at 1013.3 hPa/ °C
39043	264.21	1006.7	5.334	0.28	264.49
39044	264.01	1006.7	5.334	0.28	264.29
