Specific details on test material used for the study:

TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: the test substance was phlegmatized (15 mass% water addition) for the time of transportation. Before the study performance, the sample was dried at room temperature under vacuum conditions until a constant mass was obtained. The water content after drying process was determined using Karl Fischer method. The purity of test item after drying process was 99.88% ± 0.01%, and water content dropped to 0.391% ± 0.003%.

2		146.8	146.7
3		147.8	147.7
Average values ± standard deviations,^oC		147.4 ± 0.5	147.3 ± 0.5

3 series of boiling point measurements were performed in the following temperature ranges: sample 1: 140.0 - 400.0°C, samples 2 and 3: 135.0 - 400.0. The heating rate was 1.0 °C/min.

The table includes the average value of boiling temperature (value measured) and boiling point (value corrected according entered barometric pressure).

In this study the accuracy of the apparatus was equal to 0.5°C.

Conclusions:

The boiling point of the test item is 147.3ºC at atmospheric pressure (1015 hPa).

Executive summary:

The determination of the boiling point was carried out according to OECD Guideline No. 103 and EU method A.2 (GLP study). A preliminary study was performed in order to determine the boiling temperature range of the test item. A method according to Siwoloboff was used with the BÜCHI Melting Point M-565 apparatus. The measurements were performed in three samples of the test item. The boiling point of the test item, as average, was determined to be 147.3±0.5ºC under atmospheric pressure of 1015 hPa.
