Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of Z-Acetate is 1.3E-08 Pa (1.0E-10 mm Hg) at 20 °C and 3.5E-08 Pa (2.6E-10 mm Hg) at 25 °C as determined by the OECD 104 method.
- Executive summary:
The vapor pressure of the test substance was determined by the isothermal thermogravimetric effusion method. The weight loss of the sample was measured at 4 isothermal points between 180 and 210°C. Weight loss rate at each temperature was converted to vapor pressure and entered into linear regression analysis vs. temperature. The resulting equation was log P(T) = -7242 ×1/T + 16.83 (r = 0.995). The test was done according to EU Method A.4 “Vapour pressure” and OECD 104 “Vapour Pressure Curve” and in accord with GLP guidelines; therefore this study is classified as reliable without restrictions.
