Any other information on results incl. tables
Linear equation: log p = -2398.6*(1/T)+9.1268
Scope: from 114 to 180 °C
Nature of the change during measuring: none
Nature of the change for estimate: transition liquid-solid
Temperature of transition: 38.2 °C
Applicant's summary and conclusion
- Conclusions:
- The real value of vapour pressure for 20°C should be significantly low then the value estimated from vapor pressure curve for liquid. However the value could be used as worst case.
