The principle of steam distillation is based on Dalton's law of partial pressures. Suppose p1 and p2 be the vapour pressures of water vapour and the toluene at the distillation temperature. Toluene boils when total pressure is equal to atmospheric pressure p i.e p = p1 + p2 or p2 = p – p1 as a result when toluene boil in the presence of steam. Its partial pressure p2 is less than atmospheric pressure.

In steam distillation of toluene, the pressure of toluene in vapour is less than pressure of barometer, because it is carried out when a solid or liquid is insoluble in water and is volatile withsteam but the impurities are non-volatile.

Pressure in Steam Distillation of Toluene
Pressure in Vapor Phase:
- In steam distillation, the pressure for toluene in the vapor phase is less than the pressure of the barometer.
- This is because steam distillation involves the use of steam to facilitate the distillation process.
- The presence of steam reduces the partial pressure of toluene in the system, leading to a lower pressure compared to the barometric pressure.
Comparison with Simple Distillation:
- The pressure for toluene in vapor during steam distillation is not equal to the vapor pressure of toluene in simple distillation.
- In simple distillation, toluene is distilled without the presence of steam, leading to higher vapor pressures compared to steam distillation.
Conclusion:
- Therefore, in steam distillation of toluene, the pressure for toluene in the vapor phase is lower than the barometric pressure and not equal to the vapor pressure in simple distillation.
