Preliminary Test

Starting at 275°C, the weight of the sample decreased significantly. At 309°C, the sample weight had decreased by 25%. After the experiment, an orange molten residue remained in the sample container (original colour:Amber greasy solid). The change of the colour indicated reaction and/or decomposition of the test item.

 

Main Study

In Experiment 1, a small exothermic effect (crystallisation) and a glass transition was observed during cooling. During heating a glass transition effect was observed between -90°C and -50°C followed by several endothermic effects between -50°C and 150°C. These endothermic effects between -50°C and 150°C were most likely obtained due to melting of the test item. Starting at 200°C further endothermic effects were observed. The temperature at the maximum of the last endothermic effect between -50°C and 150°C was 49.523°C. The endothermic effects observed starting at 200°C were probably due to reaction and/or decomposition of the test item. After the experiment, a colourless molten residue remained in the sample container (original:Amber greasy solid). The change of the colour indicated reaction and/or decomposition of the test item. Boiling was not observed.

In order to investigate the endothermic effects, Experiment 2 was stopped directly after the last melting effect. The temperature at the maximum of the last endothermic effect between -50°C and 150°C was 50.013°C. After the experiment, a colourless molten residue remained in the sample container. 

In order to investigate theendothermic effects starting at 200°C, a higher heating end temperature was used in the Experiment 3. The temperature at the maximum of the last endothermic effect between -50°C and 150°C was 51.085°C. After the experiment, a light yellow molten residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item. It demonstrated that reaction and/or decomposition of the test item was the reason for the endothermic effect starting at 200°C. Boiling was not observed.

Applicant's summary and conclusion

Conclusions:
Reaction and/or decomposition of the test item was observed during the test starting at a temperature of 200°C (473K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
Executive summary:

Introduction

The study was conducted to determine the boiling temperatures of the test substance. The method used was designed to meet the requirements of the following guidelines:

  • EC Guideline A.2. Boiling Temperature. March 04, 2016
  • OECD Guideline 103. Boiling Point
  • EPA Product Properties Test Guideline OPPTS 830.7220: Boiling Point/Boiling Range. August 1996

Method

The boiling point was determined by differential scanning calorimetry (DSC). A Preliminary test followed by a main test was conducted.  The boiling temperature was determined from three experiments.

Results

 Experiment 1: starting at 200°C endothermic effects were observed which were probably due to reaction and/or decomposition of the test item.  After the experiment, a colourless molten residue remained in the sample container (original:Amber greasy solid). The change of the colour indicated reaction and/or decomposition of the test item. Boiling was not observed.

Experiment 2: After the experiment, a colourless molten residue remained in the sample container. 

Experiment 3: In order to investigate the endothermic effects starting at 200°C, a higher heating end temperature was used. After the experiment, a light yellow molten residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item. It demonstrated that reaction and/or decomposition of the test item was the reason for the endothermic effect starting at 200°C. Boiling was not observed.

 

Conclusion

Reaction and/or decomposition of the test item was observed during the test starting at a temperature of 200°C (473K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
