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., 3.074, 3.158 and 3.566 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): 170.616

Mean Peak Temperature (°C): 174.798

Mean Peak Area (mJ): 38.446

Mean ΔH (Enthalpy) J/g: 11.811

No other phase change was registered up to 430 °C.

Conclusions:

Boling point of the substance is over 430°C at 760 mm Hg.

Description of key information
