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 Test
In Experiment 1, a small exothermic effect (crystallisation) and a glass transition were 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. The temperature at the maximum of the last endothermic effect between -50°C and 150°C was 49.523°C.
Experiment 2: 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.
Experiment 3: In order to investigate the endothermic effects starting at 200°C, a higher heating end temperature was used. The temperature at the maximum of the last endothermic effect between -50°C and 150°C was 51.085°C
Experiment 4: In order to investigate the endothermic effects between -40°C and 20°C, experiment 4 was stopped directly after the endothermic effect. After the experiment, the test item residue looked the same as at start of the experiment. Because during cooling an exothermic effect was observed which probably derives from crystallisation and because at the end of the test, the test item had not molten completely, it was concluded that the endothermic effect between-40°C and 20°C was due to melting of one or more compounds present in the test item.
As complete melting was observed after the endothermic effect at approximately 50°C, the melting temperature was determined as the mean melting temperature of Experiment 1 (49.523°C), Experiment 2 (50.013°C) and Experiment 3 (51.085°C).
Applicant's summary and conclusion
- Conclusions:

- Executive summary:
Introduction
The study was conducted to determine the melting temperatures of the test substance. The method used was designed to meet the requirements of the following guidelines:
EC Guideline A.1. Melting/Freezing Temperature. March 04, 2016
OECD Guideline 102. Melting Point / Melting Range
EPA Product Properties Test Guideline OPPTS 830.7200: Melting Point/Melting Range. March 1998
Method
The melting point was determined by differential scanning calorimetry (DSC). A Preliminary test followed by a main test was conducted. The melting point was determined as the mean of three experiments.
Results
The melting temperature was determined as the mean melting temperature of Experiment 1 (49.523°C), Experiment 2 (50.013°C) and Experiment 3 (51.085°C).
Conclusion
The melting temperature of Amines, N-tallow alkyltrimethylenedi-, C4-18-alkyl phosphates was determined by differential scanning calorimetry (DSC). The melting temperature of the test item was 50.2°C (323.4K).
