Applicant's summary and conclusion
- Conclusions:
- The boiling point was aimed to be determined in a scientifically well-conducted study according to OECD TG 103, the results are hence sufficiently reliable. The boiling point was performed with the Siwoloboff method.
Signs for possible boiling indicated by a bubble chain were observed at 212.6 – 213.4 °C, the beginning was observed at 205 °C after the test item was completely melted.
The Siwoloboff method determines the boiling point by heating the test item up to the temperature where bubbles, commonly associated with boiling, are observed. The test item is allowed to cool down, and the temperature, at which no more bubbles can be observed, is defined as the boiling point
In accordance to the structural formula the observed bubbles might be a release of ammoniac caused through the heating process. The observed colourless gas confirm this.
The fact that the observed condensate was colourless could be indicative that the condensate may not be chemically identical to the residue, which further indicates that decomposition might have occurred, too
The break of the bubble chain was visible at 191.9 – 192.4 °C this might indicate decomposition as well, as this temperature is below the melting temperature.
The initially slightly beige powder turned upon heating into a brown mass, which may be indicative for decomposition. This is supported by the available melting point determination, in which heating was continued to temperatures higher than the observed melting point. In this study, melting started at 202°C, decomposition started at 206°C, most probably due to ammonia elimination based on the test item's molecular structure. It can be hence concluded that a similar observation was made in the present study.
Therefore no boiling point of Ammonium-3-nitrobenzoate could be determined because of supposed decomposition of the test at 205 °C ( 478.15 K).
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid. - Executive summary:
The boiling point was determined according to OECD 103 resp. EU A.2 under GLP following the Siwoloboff method.
Signs for possible boiling indicated by a bubble chain were observed at 212.6 – 213.4 °C, the beginning was observed at 205 °C after the test item was completely melted.
In accordance to the structural formula the observed bubbles might be a release of ammoniac caused through the heating process.
Therefore no boiling point of Ammonium-3-nitrobenzoate could be determined because of supposed decomposition of the test at 205 °C (478.15 K).
