Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Principles of method if other than guideline:
Different quantities viz., 2.78, 3.33 and 3.15 mg test item for replication I, II and III were weighed in a separate tarred sample pan using a balance. The balance was allowed to stand to stabilize. After the balance stabilization, the weight (mg) of the test item was recorded. The sample pan was sealed and placed in the instrument (DSC) and the weight (mg) of the test item was entered into the instrument (DSC) for the respective replications. The heating was started from 30 °C to 430 °C at a rate of 10 °C/min in presence of nitrogen. The onset temperature (°C), peak temperature (°C), peak area (mJ) and the ΔH (enthalpy) J/g were calculated using the software. The experiment was carried out in three replications.
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Boiling pt.:
> 430 °C
Atm. press.:
760 mm Hg
Decomposition:
no

The test item when heated from 30 °C to 430 °C @ 10 °C/minute in presence of nitrogen in three replications had one endothermic peak, the mean onset temperature (°C), mean peak temperature (°C), mean peak area (mJ) and the mean ΔH (enthalpy) J/g recorded is provided below:

Mean Onset Temperature (°C): 289.156

Mean Peak Temperature (°C): 290.940

Mean Peak Area (mJ): 836.112

Mean ΔH (Enthalpy) J/g: 311.961

No phase change was registered up to 430 °C.

Conclusions:
Boiling point of the substance is over 430°C at 760 mm Hg.
