Optimizing Büchi® Rotary Evaporator Applications

(atmospheric pressure)
Tp = vapor pressure temperature (°K) at pressure p (mbar)
b = constant b

Example:

What vacuum pressure should be set for the evaporation of ethanol at a vapor pressure temperature of 40°C?

Bp = 78°C
Constant b = 0.159

Log P = 3.006 [Ts Tp]
_______

[b Tp]

Log P = 3.006 [351 313]

[0.159 313]

= 2.24

p = 174.7 mmbar

The nomogram (Table B) can also be used to extrapolate the appropriate vacuum pressure for an application.

Calculating the rate of evaporation

The rate of evaporation is dependent on the difference between the vapor pressure temperature (boiling point under vacuum) and the bath temperature as well as the rotational speed of the evaporation flask. The rate of evaporation of any solvent can be calculated by using the following formula:
