During the main study the DSC-cell was opened in an ambient environment at a celltemperature of 0°C during the transfer of the sample container into the cell. This low temperature was selected to avoid evaporation of the test item as much as possible but within the time the cell was open, water had condensated into the cell causing exothermic and endothermic effects between -50°C and 50°C when cooling and heating the sample.

Experiment 4: During cooling no effects were observed which were due to crystallization of the test item. During heating an endothermic peak between -25°C and 100°C was observed. The extrapolated onset temperature of the peak was 75.88°C. The effect was due to boiling of the test item. After the experiment it was observed that the test item had evaporated from the sample container.

Experiment 5: To investigate the boiling peak, a closed sample container was applied in the Experiment 5. The extrapolated onset temperature of the boiling peak was 114.862°C. Since the endothermic peak shifted to a higher temperature this confirms that boiling of the test item was the reason for the endothermic effect. After the experiment, it was observed that the test item had evaporated from the sample container.

Experiment 6: Experiment 6 was performed as a duplicate of Experiment 4. The extrapolated onset of the boiling peak was 75.287°C. After the experiment it was observed that the test item had evaporated from the sample container.

The boiling temperature was determined as the average boiling temperature obtained from experiment 4 (75.880°C) and Experiment 6 (75.287°C).

Conclusions:
The boiling temperature of Sulfonyl vinyl ether perfluorurate was determined at 75.6°C (348.7K) by using DSC. The atmospheric pressure was 1006 ± 1 hPa.
Executive summary:

The boiling temperature of Sulfonyl vinyl ether perfluorurate (CAS 29514-94-1) was determined using differential scanning calorimetry (DSC). The test was performed according to the OECD Guidelines for the Testing of Chemicals no. 103: "Boiling Point ", 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 Sulfonyl vinyl ether perfluorurate was determined at 75.6°C (348.7K) by using DSC (Differential Scanning Calorimetry).

Description of key information

One reliable key study (Klimisch 1) is available. The boiling point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 103,EU Method A.2 and EPA OPPTS 830.7220) and GLP.

No deviations from the guidelines were observed during the test.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
