Summary
Nylon is formed at the interface between aqueous 1,6-diaminohexane layered with adipoyl chloride dissolved in cyclohexane. The nylon fiber is pulled from the interface and coiled around a test tube.
Hazards
- Adipoyl Chloride is corrosive and a lachrymator.
- Cyclohexane is flammable and malodorous.
- 1,6-diaminohexane is corrosive.
Chemicals and Solutions
- 5% 1,6-diaminohexane (aq)
- 5% adipoyl chloride in cyclohexane
Materials
- Nested crystallizing dishes
- Large test tube or paper roller
- Forceps
- Gloves
- Absorptive pad
Procedure
- Add 25ml of the 5% 1,6-diaminohexane aq. to the inner crystallizing dish.
- Carefully layer 25ml of the 5% adipoyl chloride in cyclohexane on top of the aqueous ammine. Do not allow solutions to mix.
- Pluck the film from interface with forceps. Pull slowly and with and even and constant motion to form the nylon polymer. Lay the filament over a large test tube and roll to form a continuous thread of polymer.
