Glycerol is separated in soap industries by;
Glycerol is separated in soap industries by;
The correct option is B Distillation under reduced pressure
Answer (C)
Explanation for correct option:
(B) Glycerol is separated in soap industries by distillation under reduced pressure. Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy.
Explanation for incorrect option:
(A) Fractional distillation-This distillation involves separation of miscible liquids .
(C) Differential distillation- This distillation is a process in which a single component from a liquid is converted into vapor, the vapor is transferred to another place and recovered by condensing it.
(D) Steam distillation- Steam distillation is a process for temperature sensitive substances.
Hence option (B) is correct option.
