Any other information on results incl. tables

This handbook report also an equation for the calculation of the vapour pressure of benzotrichloride:

log Pv= A + B/T + C x log T + D x T + E T²

P: mmHg

T: K

A= 0.4912

B= -2.7285E+03

C= 4.4706

D= -1.0580E-02

E= 4.7621E-06

Validity of the equation when T is between 268 and 737 K.

Applicant's summary and conclusion

Conclusions:
The reported values for the vapor pressure of benzotrichloride are:
9°C - 10 Pa
40.6°C - 100 Pa
81.5°C - 1 kPa
136.2°C - 10 kPa
213.0°C - 100 kPa
Executive summary:

Data from handbook of Vapor Pressure: the values reported by this handbook for the vapor pressure of benzotrichloride are:

9°C - 10 Pa

40.6°C - 100 Pa

81.5°C - 1 kPa

136.2°C - 10 kPa

213.0°C - 100 kPa

Besides, this handbook reports an equation that allows calculation of the vapour pressure at 20°C. Using this equation the vapour pressure at 20°C is 0.42 hPa.
