Solution
Destructive distillation
The process of heating coal in the absence of air is called the destructive distillation of coal. Coal contains a number of elements such as carbon, hydrogen, oxygen, nitrogen, and sulphur. When coal is heated in the absence of air, a number of products are obtained.
- Sugar charcoal is a type of plant charcoal, obtained from cane sugar. It can be obtained by the destructive distillation of cane sugar or by adding concentrated sulphuric acid (H2SO4) to cane sugar.
Conc. H2SO4 is used because it is a strong dehydrating agent and absorbs water from the cane sugar leaving behind pure carbon i.e. charcoal.
Sugar charcoal can be obtained by Destructive distillation of sugar with concentrated acid.
