The equation of the curve was: log PT,20 = -1364 x 1/T + 5.90 (r = 0.998, n = 14).

The vapour pressure of the test item at 20°C and 25°C was determined as the mean values obtained with experiment 1 and 2.

Applicant's summary and conclusion

Conclusions:
The static method was applied for the determination of the vapour pressure of dichloro trifluoro methoxy dioxolane.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was 18 kPa (equivalent to 1.4 x 10+2 mm Hg) and 21 kPa (equivalent to 1.6 x 10+2 mm Hg), respectively.
Executive summary:

The vapour pressure of dichloro trifluoro methoxy dioxolane (CAS 161611 -73 -0) 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 18 kPa (equivalent to 1.4 x 10+2 mm Hg) and 21 kPa (1.6 x 10 +2 mm Hg), respectively.
