Materials and methods

Test guideline
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
Principles of method if other than guideline:
Visual assessment. Boiling point determined using a BUCHI B-545 Melting point/Boiling point apparatus by visual assessment. The apparatus uses melting point standards for calibration.
GLP compliance:
yes
Type of method:
other: Visual assessment, comparable to the principle according to Siwoloboff and the photocell method.

Results and discussion

Boiling point
Boiling pt.:
378.6 °C
Atm. press.:
1.013 hPa

Any other information on results incl. tables

Test 1: 378.7 °C

Test 2: 378.5 °C

The changes in colouration of the test substance with increasing temperature indicated that the test substance may have decomposed before the boiling point was reached. However a reproducible end point was reached and this value therefore will be quoted.

Applicant's summary and conclusion

Executive summary:

The test was carried out on one sample in duplicate.

The test was carried out with a BUCHI B-545 Melting point/Boiling point apparatus by visual assessment. This method is believed to be comparable to the principle according to Siwoloboff and the photocell method.

The instrument was calibrated with a cafeine standard.

Boiling point (mean): 378.6 °C

The changes in colouration of the test substance with increasing temperature indicated that the test substance may have decomposed before the boiling point was reached. However a reproducible end point was reached and this value therefore will be quoted.
