TGA EXPERIMENT (PRELIMINARY TEST)
Decrease of weight from 225°C upwards: 25% at 272°C and 70% at 292°C.
After the experiment it was observed that the test item was evaporated from the sample container.
DSC EXPERIMENT 1
During cooling, two exothermic effect between -30°C and -60°C were found. The effect was obtained due to crystallization of the test item.
During heating two exothermic effects were observed between -50°C and 0°C followed by an endothermic effect observed between 0°C and 25°C. The exothermic effect was obtained by crystallisation. The endothermic effect was obtained by melting. The extrapolated onset temperature of the melting effect was 6.431°C. Between 200°C and 300°C an endothermic effect was observed. The extrapolated onset temperature of the second endothermic effect was 289.350°C. The endothermic effect was most likely obtained due to boiling of the test item. After the experiment it was observed that the test item had evaporated from the sample container.
DSC EXPERIMENT 2
In order to investigate the second endothermic effect, a higher heating rate of 50°C/minute was used. The extrapolated onset temperature was 289.730°C. The endothermic effect had not shifted to higher temperatures. It demonstrated that boiling of the test item caused the endothermic effect. After the experiment it was observed that the test item had evaporated from the sample container. Since a higher heating rate was used, the extrapolated onset temperature was not used in the calculation of the boiling point.
DSC EXPERIMENT 3
Experiment 3 was performed as a duplicate of Experiment 1. Similar results were obtained. The extrapolated onset of the melting effect was 6.369°C. The extrapolated onset of the boiling effect was 289.127°C. After the experiment it was observed that the test item had evaporated from the sample
DSC curves recorded during heating: see illustration below.
RESULT
Melting temperature: mean extrapolated onset temperature of Experiment 1 (6.431°C) and Experiment 3 (6.369°C).
Boiling temperature: the mean extrapolated onset temperature of DSC Experiment 1 (289.350°C) and DSC Experiment 3 (289.127°C).
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of the substance was determined to be 6.4°C.
- Executive summary:
The melting and boiling temperature of the test item were determined in a GLP study using Differential Scanning Calorimetry. The experiments were in accordance with EC A.1, OECD 102 and OPPTS 830.7200 (melting temperature) and on EC A.2, OECD TG 103 and OPPTS 830.722 (boiling temperature).
Two endothermic effects appeared in the temperature range between -90°C and 400°C due to melting and boiling. The melting temperature of the substance was determined to be 6.4°C (mean extrapolated onset temperature of duplicate experiments). The boiling temperature of the substance (at 1026 ± 4 hPa) was determined to be 289.2°C (mean extrapolated onset temperature of duplicate experiments).
