Any other information on results incl. tables

Linear equation: log p = -2964.5*(1/T)+9.4551

Scope: from 183 to 393 °C

Nature of the change during measuring: none

Nature of the change for estimate: transition liquid-solid

Temperature of transition: 145.3 °C

Applicant's summary and conclusion

Conclusions:
The real value for 20°C should be 1000x lower than extrapolated value; extrapolated value is out of scope, moreover there is a liquid-solid transition
