Class 12 Chemistry Organic Compounds Lecture 5, Destructive Distillation of Coal Experiment
What we will learn in this video?
destructive distillation of coal Laboratory technique
The method involved with heating of coal without a trace of oxygen or air to acquire valuable items is known as destructive distillation of coal.
At the point when coal is heated firmly over 1000 C without air or oxygen, it produces numerous important byproducts.

The fundamental byproducts are:

• coke

• coal tar

• ammoniacal alcohol

• coal gas


Let’s understand the concept of destructive distillation through experiment
The materials needed for the experiment of destructive distillation are as follow:
Two hardboiling glass test tubes marked as A and B, 2 delivery tubes, clamp stand, burner, rubber stoppers, powdered coal and water.
Procedure
• Take little powdered coal in test tube A.
• Test tube A is fitted with a rubber stopper carrying a delivery tube and is clamped to the stand.
• Test tube B containing water is clamped vertically to the stand.
• The burner is lighted and the test tube A is heated first gently and then intensely.
• The gas liberated by heated coal pass through the water in test tube B.
• You will notice dark coal tar settled down at the lower part of test tube B.
• The ammoniacal compounds formed will dissolve in water in test tube B to form ammoniacal liquor.
• Coal gas insoluble in water escapes through the side delivery tube. It can be lighted at the end of the open tube. It is a mixture of hydrogen, methane, carbon monoxide and other gases.
• Solid hard black residue left behind in test tube A is coke. It is an almost pure form of carbon.

Destructive Distillation of Coal is also explained with the help of following points:
