Question

which method is used for separating Glycerol from Spent-lye in the soap industry?

Answer 1

Answer:

The distillation

Explanation:

The distillation technique most sited for separating glycerol from spent lye in the soap industry

Answer 2

which method is used for seperating Glycerol from spent lye in the soap industry ?

1. fractional distillation
2. steam distillation
3. simple distillation
4. reduced pressure distillation

solution : The most suitable method is distillation under reduced pressure . because Glycerol is high boiling liquid and we have a method in which it decomposes below its boiling point.

distillation under reduced pressure is the perfect method for seperating Glycerol from spent-lye in the soap industry, in this method liquid is made to boil at lower temperature than its normal temperature by lowering the pressure on its surface.

Therefore the correct option is (4)
