Solvent data
The graph shows the relationship between the pressure and vapor temperature of a
selection of solvents.
Torr to mbar conversion: [mmHg] ≈ 3/4 [mbar]
The temperature difference between the vapor temperature and the
cooling medium should be at 20 K to result in sufcient condensation.
The temperature difference between the heating bath and vapor
temperature should be at 20 K to reach a sufcient Distillation rate (dT).
i.e.: Set a vacuum for a vapor point at 40 °C, set the heating bath
temperature at 60 °C.
