There are basically two possibilities for optimising distillation:
1. Slowly reduce pressure again
Bath must have reached 60 °C (Boiling point is reduced,
increase of
Δ
T1, resulting in increase of distillation capacity)
or
2. increasing bath temperature
(Increase of
Δ
T1, resulting in increase of distillation capacity).
By increasing the bath temperature, not all of the additional
energy is supplied to distillation, but more is also discharged
into the environment. This is due to the increase temperature
difference between bath and environmental temperature.
