- Key result
- Boiling pt.:
- 19.5 °C
- Atm. press.:
- 1 007 hPa
- Conclusions:
- The boiling temperature of the substance MOVE3 at 1007 hPa was determined to be 19.5°C.
- Executive summary:
The boiling temperature was determined using Differential Scanning Calorimetry in a GLP study according to EC A.2, OECD 103 and OPPTS 830.7220.
No deviation from the guideline was observed during the study.
From duplicate experiments using an aluminum sample crucible closed by a lid with a small prefabricated hole, a mean value of 19.5°C was obtained for the boiling temperature of the substance MOVE3 at 1007 hPa.
Reference
Preliminary test (TGA experiment)
It was observed that the test item (10.9 mg) evaporated very quickly. The weight of the test substance had already been reduced to 1.25 mg at the start of the experiment. DSC experiments were therefore performed up to an end temperature of 75°C.
Main test:
DSC EXPERIMENT 1
An endothermic peak between -60°C and 10°C was observed. The extrapolated onset temperature of the peak was -18.10°C. The effect was most likely obtained due to evaporation of the test substance. After the experiment it was observed that the test substance had evaporated from the sample container. The peak shape showed that the hole drilled in the sample container was too large. The result of Experiment 1 was not used for calculations.
DSC EXPERIMENT 2
In an attempt to obtain a better peak shape, a sample container with a prefabricated hole in the sample pan was used. The extrapolated onset temperature of the evaporation peak was 19.40°C. After the experiment it was observed that the test substance had evaporated from the sample container.
DSC EXPERIMENT 3
The temperature program (as well as the use of a sample container with a prefabricated hole) was similar as the temperature program of Experiment 2. Similar results as with Experiment 2 were obtained. The extrapolated onset of the evaporation peak was 19.67°C. After the experiment it was observed that the test substance had evaporated from the sample container.
The boiling temperature of the substance was calculated as the average boiling temperature obtained from Experiment 2 (19.40°C) and Experiment 3 (19.67°C).
Description of key information
The boiling temperature was determined using Differential Scanning Calorimetry in a GLP study according to EC A.2, OECD 103 and OPPTS 830.7220.
No deviation from the guideline was observed during the study.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 19.5 °C
