Any other information on results incl. tables
1) Preliminary test:
From the start of the measurement upwards the weight of the sample decreased significantly. At 61°C the sample weight had decreased by 25%. After the experiment it was observed that the test item was evaporated from the sample container.
2) Main study
Three different experiments (1, 2 and 3) were performed within the mains tudy.
During heating in experiment 1, an endothermic peak between 50°C and 100°C was observed. The extrapolated onset temperature of the peak was 76.447°C. The effect was most likely obtained due to boiling of the test item. After the experiment it was observed that the test item was evaporated from the sample container.
To further investigate the boiling peak a closed sample container was applied in the Experiment 2. In a closed sample container gas pressure built up above the test item is higher than in an open sample container (where it equals atmospheric pressure). In this way boiling is observed at higher temperatures. The extrapolated onset temperature of the boiling peak in the closed sample container was 115.179°C. As can be seen the endothermic peak shifted to higher temperatures. It demonstrated that boiling of the test item was the reason for the endothermic effect. Another endothermic signal was observed at approximately 225°C. As a comparable signal was not observed in Experiment 1, it was considered an artefact. A mechanical shock may have caused it. After the experiment it was observed that the test item was evaporated from the sample container.
Experiment 3 was performed to determine the duplicate boiling temperature of the test item. The extrapolated onset of the boiling peak was 76.007°C. After the experiment it was observed that the test item was evaporated from the sample container.
The boiling temperature was determined as the average boiling temperature obtained from experiment 1 (76.447°C) and experiment 3 (76.007°C).
Applicant's summary and conclusion
- Conclusions:
- The boiling point of dichloro trifluoro methoxy dioxolane was determined at 76°C (349K) by using DSC (Differential Scanning Calorimetry).
- Executive summary:
The boiling temperature of dichloro trifluoro methoxy dioxolane (CAS 161611-73-0) was determined using differential scanning calorimetry (DSC). The test was perforemd according to the OECD Guidelines for the Testing of Chemicals no. 102: "Melting Point / Melting Range", July 27, 1995 and was GLP compliant.
The boiling temperature of the test item was evaluated from the DSC curve as the extrapolated onset temperature of the endothermic melting peak.
The boiling temperature of dichloro trifluoro methoxy dioxolane was determined at 76°C (349K) by using DSC (Differential Scanning Calorimetry).
