- STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature. - Key result
- Boiling pt.:
- 305.4 °C
- Atm. press.:
- 1 009 hPa
- Decomposition:
- no
- Conclusions:
- The boiling point of the test item was observed at temperature of 305.4 ± 0.4 ºC under atmospheric pressure of 1009 hPa.
- Executive summary:
The determination of the boiling point was performed according to OECD 103 (Boiling point) and EU method A.2. (Method according to Siwoloboff), following GLP. The capillary tube in heated metal block method and BÜCHI Melting Point B-565 apparatus was used. A preliminary study was carried out in order to determine the boiling temperature range for the test item. The preliminary study and measurements were performed under atmospheric pressure of 1009 hPa. The three series of measurements were performed in the temperature range 100 - 400 ºC. The average value of boiling point was found automatically at 305.4± 0.4 ºC.
Reference
The measurements were done automatically when the value frequency of air bubbles evolved from an inner capillary was 0.6 Hz.
The three series of measurements were performed in the temperature range 100 - 400 ºC. Below the temperature of 290 ºC, the temperature gradient of 3 ºC/min was used. Above 290 ºC the used gradient was 0.5 ºC/min (at about 10.0 ºC below the expected boiling temperature).
The average value of boiling point was found automatically at 305.4 ± 0.4 ºC. The values of boiling point for the three samples of test item are shown in table 2.
