- Executive summary:
The determination of the boiling point of the test item was carried out according to EU method A.2 (method according to Siwoloboff) / OECD 103 (GLP study). The decomposition of the test item was observed at a temperature of 277.6 ± 0.3 °C, below the boiling point.
Reference
In the course of the study, the decomposition of the test item had been observed (sample darkening about 277.6 ± 0.3 °C) after the melting point was reached. All samples were decomposed below the boiling point. At temperature about 290 °C the colour of test item in capillary was dark brown.
