Storage Room Temperature temperature (20 ± 5 °C), keep away from light - Key result
- Boiling pt.:
- 272.3 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Remarks on result:
- other: Decomposition was indicated by colour change and physical state change
- Conclusions:
- The boiling point of the test substance ROC-601 was determined with 272.3 ± 0.2 °C (545.4 ± 0.2 K) under decomposition.
- Executive summary:
The boiling point of the test substance was determined following the SIWOLOBOFF method. The boiling point under decomposition was determined with 272.3 ± 0.2 °C (545.4 ± 0.2 K).
This value is the mean of two independent determinations ± their standard deviation.
Decomposition was indicated by colour change and physical state change. As the test item decomposed during boiling, correction to standard pressure (101.325 kPa) using the Sidney-Young equation was not applied.
