(C) In the soap industry,glycerol is obtained as a byproduct. It is separated from the spent lye by the process of distillation under reduced pressure. This is because glycerol has a high boiling point and tends to decompose at its normal boiling point. By reducing the pressure,the boiling point is lowered,allowing it to be distilled without decomposition.
