Linear regression was determined using Antoine equation:
Pvap, mmHg = exp[-2576.558494/(T°C+140) + 15.490704]; R² = 0.999999
Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of DONOL at 20 °C is 0.5 mmHg (ASTM E-1719-97).
- Executive summary:
The vapor pressure of DONOL was measured using the dynamic method. Vapor pressure and temperature were measured at a variety of equilibrium points and fit to the Antoine equation. The extrapolated vapor pressure was then determined. The study was conducted in accordance with ASTM E-1719-97 but was not GLP compliant. Therefore, the study is classified as acceptable with restrictions.
