Vapour pressure
- Temp.:

- Vapour pressure:
- 0.009 Pa
Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of laurylimidazole is 0.0088 Pa at 20°C.
- 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 90 and 120°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) = -4327 ×1/T + 12.70 (r = 0.9994). The test was done according to EU Method A.4 “Vapour pressure” and OECD 104 “Vapour Pressure Curve” and in accord with GLP guidelines, and the thermogravimetric analysis method is particularly suited to substances of low vapor pressure (10E-10 Pa to 1 Pa). Therefore this study is classified as reliable without restriction.
