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.
