in soap industry?
a. Distillation under reduced pressure
b. Fractional distillation
c. Filtration
d. Crystallization
Which technique is widely used in​

Answer 1

The distillation technique most suited for separating glycerol from spent-lye in the soap industry is:
(a)Distillation under reduced pressure

Reason :

Glycerol is high boiling liquid with boiling point 290°C. It can be separated from spent lye by the method of distillation. In this method, liquid is made to boil at lower temperature than its normal temperature by lowering the pressure on its surface. So if the external pressure is reduced, then the boiling point of the liquid is lowered. Hence, glycerol can be obtained without its decomposition at high temperature.
