Aliquots of about 0.005 g of the test substance were weighed into aluminium crucibles with either pre-perforated or manually pierced lids. The boiling temperature was determined in six independent runs using a differential scanning calorimeter.
Determination 1: 0.0050 g, pre-perforated lid
Determination 2: 0.0048 g, pre-perforated lid
Determination 3: 0.0050 g, manually pierced lid
Determination 4: 0.0055 g, manually pierced lid
Determination 5: 0.0048 g, manually pierced lid
Determination 6: 0.0051 g, manually pierced lid
A Mettler Toledo DSC822 calorimeter with a ThermoHaake Cooler EK45/MT was used. The temperature program was started at 20 °C and the samples were heated up to 450 °C with a rate of 20 °C/minute. Determinations 1 to 4 were done under static air and determinations 5 and 6 under nitrogen atmosphere. The thermograms of the determinations 1 and 2 (with pre-perforated lids) with an elevated endotherm start temperature indicated boiling of the test substance, whereas the remaining residue for all determinations confirmed a degree of decomposition that was associated with this process. Therefore, the boiling temperature was determined on the basis of runs 1 and 2 only. An approximate boiling temperature of 325 °C at an atmospheric pressure of 100.8 kPa was determined. From the residu remaining after all determinations it was confirmed that decomposition occurred both in air and under a nitrogen atmosphere, indicating the process was most likely thermal and not oxidative.
Applicant's summary and conclusion
- Conclusions:
- The boiling temperature was determined to be about 325 °C at a pressure of 100.8 kPa. Boiling was associated with decomposition.
- Executive summary:
The boiling temperature of the substance was studied under GLP to OECD TG 103, using a differential scanning calorimeter. Aliquots of about 0.005 g of the test substance were weighed into aluminium crucibles with either pre-perforated or manually pierced lids. The boiling temperature was determined in six independent runs using a differential scanning calorimeter. Two runs with pre-perforated lids and four runs with manually pierced lids were performed. A Mettler Toledo DSC822 calorimeter with a ThermoHaake Cooler EK45/MT was used. The temperature program was started at 20 °C and the samples were heated up to 450 °C with a rate of 20 °C/minute. Determinations 1 to 4 were done under static air and determinations 5 and 6 under nitrogen atmosphere. The thermograms of the determinations 1 and 2 (with pre-perforated lids) with an elevated endotherm start temperature indicated boiling of the test substance, whereas the remaining residue for all determinations confirmed a degree of decomposition that was associated with this process.
