Question:

$\text{The distillation technique most suited for separating glycerol from spent-lye in the soap industry is:}$ $1. \text{ Steam distillation}$ $2. \text{ Distillation under reduced pressure}$ $3. \text{ Fractional distillation}$ $4. \text{ Differential extraction}$

Options:

1. $\text{Steam distillation}$
2. $\text{Distillation under reduced pressure}$
3. $\text{Fractional distillation}$
4. $\text{Differential extraction}$

Solution:

$\text{Hint: liquids that decompose at or below their boiling points}$ $\text{Distillation under reduced pressure is the technique most suited for the separation of Glycerol from Spent-lye (Soap Solution obtained from basic hydrolysis of fats)}$
