Conclusions:
The static method was applied for the determination of the vapour pressure of Sulfonyl vinyl ether perfluorurate .
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was 12 kPa and 15 kPa respectively.
Executive summary:

The vapour pressure of Sulfonyl vinyl ether perfluorurate (CAS 29514-94-1) was determined using the static method according to the OECD guideline 104 "Vapour Pressure", March 23, 2006. the study was performed in compliance with GLP principles.

The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was 12 kPa (equivalent to 9.3 x 10E1 mm Hg) and 15 kPa (1.1 x 10E2 mm Hg), respectively.

Description of key information

One reliable key study (Klimisch 1) is available. The vapour pressure of the test item was determined with the static method according to recognized guidelines (EU Method A.4, OECD Guideline 104 and EPA OPPTS 830.7950) and under GLP.

No deviations from the guideline were observed during the test.

Key value for chemical safety assessment

Vapour pressure:
12 kPa
at the temperature of:
20 °C
