Linear regression analysis of the log P(T) values and 1/T was performed using a least squares method. The vapor pressure of the test substance at 20 °C and 25 °C were determined using the vapour pressure regression curve. The equation of the curve was: log P(T) = -1803 ×1/T + 9.82 (r = 0.9997, n = 18).

Conclusions:

The vapor pressure of PPVE-2 is 4.7E03 Pa (35 mm Hg) at 20 °C and 6.0E03 Pa (45 mm Hg) at 25 °C as determined by EU Method A.4.

Executive summary:

The vapor pressure of the test substance was determined by the static method. The vapor pressure of the test item at 5 °C intervals from 40 °C to 80 °C was determined and entered into linear regression. The resulting equation was log P(T) = -1803 ×1/T + 9.82 (r = 0.9997). The test was done according to EU Method A.4 and in accord with GLP guidelines; therefore the study is considered reliable without restriction.

Conclusions:

A vapor pressure of 3060 Pa at 20 °C was reported for PPVE-2 by a dynamic method.

Executive summary:

A dynamic method was used to test the vapor pressure of PPVE-2. A result of 3060 Pa at 20 °C was included in the report. The study did not list testing lab, guideline, nor GLP compliance. No information is available on test substance composition; therefore, the documentation is insufficient for assessment.

Description of key information

The vapor pressure of PPVE-2 is 4.7E03 Pa (35 mm Hg) at 20 °C and 6.0E03 Pa (45 mm Hg) at 25 °C as determined by EU Method A.4.

Additional information

In the key study, the vapor pressure of the test substance was determined by the static method. The vapor pressure of the test item at 5 °C intervals from 40 °C to 80 °C was determined and entered into linear regression. The resulting equation was log P(T) = -1803 ×1/T + 9.82 (r = 0.9997). The test was done according to EU Method A.4 and in accord with GLP guidelines; therefore the study is considered reliable without restriction. In one supporting study, a dynamic method was used to test the vapor pressure of PPVE-2. A result of 3060 Pa at 20 °C was included in the report. The study did not list testing lab, guideline, nor GLP compliance. No information is available on test substance composition; therefore, the documentation is insufficient for assessment. In another supporting study, a vapor pressure of 4079.7 Pa (30.6 mm Hg) at 20 °C was reported for PPVE-2. Only the result was reported on the SDS and no information about the method used was provided; therefore the reliability of the data is not assignable.
