- Key result
- Boiling pt.:
- 196.3 °C
- Atm. press.:
- 990 hPa
- Conclusions:
- The boiling point was 196.3 ± 0.4 ºC at 990 hPa.
- Executive summary:
The determination of the boiling point was performed according to OECD Guideline 103 and EU Method A.2 (GLP study) using the method according to Siwoloboff. The average value of an initial boiling point of the test item was determined to be 196.3 ± 0.4 °C under atmospheric pressure of 990.0 hPa.
Reference
The value of the boiling point was determined automatically. The preliminary study and measurements were performed under atmospheric pressure of 990.0 hPa. The preliminary study was carried out in order to determine the boiling temperature range. The study was performed in the temperature range 30.0 - 230.0 °C. The value of an initial boiling point was found at 198.9°C when heated at 10.0 °C per minute starting at 30.0°C. The three series of measurements were performed in the temperature range 190.0 - 390.0 °C. Below the temperature of 190.0°C, the temperature gradient of 3°C/min was used. Above 190.0°C the used gradient was 1.0°C/min. The average value of an initial boiling point for the three samples is 196.3 ± 0.4 °C.
