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.
