- Executive summary:
A study was conducted to determine the boiling point of the test substance according to EU Method A.2. using BÜCHI melting point B-545 apparatus. A preliminary study was carried out to determine the boiling temperature range. For the main study, heating was conducted at 10.0 K/min starting at 373.15 K. At approximately 10.0 K below the expected boiling temperature, heating was reduced to 3.0 K/min. The boiling point was read when a quick continuous flow of bubbles (such as a string of pearls) was formed at the lower open end of the capillary and disappeared when liquid suddenly rose in the boiling capillary. The average value of the initial boiling point was determined to be 568.85 ± 0.4 K (295.7°C) at atmospheric pressure (102.1 kPa) (Olszewska, 2010).
