CAS number: 4573-50-6
In the temperature range of -50 to -20 °C an endothermic effect
(melting) was observed. Between approx. 120 - 260 °C a second
endothermic effect (boiling) could be detected.

During the cooling phase, an exothermal effect was observed in the
temperature range of -60 to -70 °C, which can be assigned to the
freezing of the test item. During the heating phase a distinct
endothermic effect was observed in the temperature range of -50 to -20
°C, which can be assigned to the melting of the test item.
The test item showed a second endothermic signal in the temperature
range of approx. 120 - 260 °C that can be assigned to the boiling of the
For the correction of the boiling temperature to standard pressure the
test item was assigned to chemical group 2 (e.g. Hydrocarbons). A
correction value φ = 5.0 was used for the temperature of 230 - 240 °C.
The lowest measured onset temperature is corrected to the standard
pressure to be 235.0 °C and the highest onset temperature to be 235.12
°C. As the corrected onset temperatures in both tests deviate less than
0.5 K from their mean value of 235.06 °C, the test item has a boiling
point of 235.0 °C.
No further thermal effects were observed up to the maximum test
temperature of 500 °C.
The test item has a boiling point of 235.0 °C corrected to normal
atmospheric pressure (1013 hPa) as determined by differential scanning
calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD
Test Guideline 103 (1995).
Boiling point: 235.0 °C at 1013 hPa (EU Method A.2, differential
The boiling point has been corrected to normal pressure (1013.25 hPa)
using the H.N. Hass and R.F. Newton equation.
