- Executive summary:
A study was conducted according to OECD TG 103, Regulation (EC) No 440/2008 method A.2 and EPA OPPTS 830.7220 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed out into a 40 µL aluminium crucible under an inert atmosphere (nitrogen). Two tests were performed. As reference crucible, an empty aluminium crucible was used. The crucibles were heated from room temperature up to 500 °C at a constant heating rate of 10 °C/min. The appearance of the test item was noted before and after the test. A supplementary test using the capillary method was performed with the test item. A preliminary and a main test using this method were performed. In the DSC measurement the boiling point was determined to be in the range of 86.8 – 100.9 °C (359.9 – 374.0 K) at atmospheric pressure (101.17 kPa). According to the supplementary test with capillary method the boiling point was determined to 102.9 °C (376.1 K) at 99.41 kPa.
Reference
Appearance of the Samples
Before the test the appearance of the test item was colourless liquid. After the experiments the test item was evaporated from the crucible.
Results – DSC method
Using a linear heating rate of 10 °C/min the boiling point of the test item was determined to be in the range of 86.8 – 100.9 °C (359.9 – 374.0 K) at atmospheric pressure (101.17 kPa).

Supplementary Test – Capillary method
The apparatus was checked with ultrapure water. The literature boiling point of water is 100 °C. The measured value corresponded to the literature value. The boiling point of water was determined to be 100.3 °C (373.5 K). Measured values were determined to be in the required range (literature value ± 0.5 °C).
Capillary method - Preliminary Test
Preliminary test with the test item was performed before the main test.

Capillary method – Main test
For the main study the metal block was heated to 92 °C. The capillaries containing the test item were placed into the apparatus and the temperature was raised at 0.5 °C/min heating rate until the boiling temperature was reached. Three tests were carried out. The boiling point was determined to be 102.9 ± 0.57 °C (95 % confidence interval) i.e. 376.1 K. At the end of the measurements the colour of the samples became slightly yellow.
