Place 30 mls of adipyl chloride into a small beaker. Slowly add 30 mls of hexamethylene diamine. Hexamethylene diamine should float on the surface of the adipyl chloride.

Note - Adipyl chloride comes dissolved in dichloroethane. Dichloroethane is no longer recommended in schools. Use hexane to dissolve apilyl chloride.

A polymerisation reaction occurs where the two liquids come into contact with each other. The reaction produces nylon. Gloves and goggles must be worn for this demonstration.

.

Nylon can also be made from 1,6-diamoinhexane and hexane-1,6-dioic acid.

The monomers join to form nylon with expulsion of a water molecule at every bond.

This type of reaction is known as a condensation reaction.
