The distillation technique most suited for separating glycerol from spent - lye in the soap industry is:
Steam distillation
Distillation under reduced pressure
Simple distillation
Fractional distillation
Solution
Glycerol (B.P. ) is separated from spent - lye in the soap industry by distillation under reduced pressure, as for simple distillation very high temperature is required which might decompose the component.
