Chemicals |
|
250 mL beaker |
Solution 1 – 50 mL 0.5M Hexamethylenediamine in 0.5 NaOH (3.0g Hexamethylenediamine and 1.0 g NaOH in 50 mL DI water) |
|
Stirring rod |
|
|
Hooked spatula |
Solution 2 – 50 mL 0.2 Sebacoyl Chloride in hexane (2.14 mL Sebacoyl Chloride in 50 mL in hexane) |
|
Wash bottle |
|
Procedure:
- Wearing gloves, place Solution 1 in the beaker. Food coloring can be added to this layer to enhance visibility of the interface.
- Slowly pour Solution 2 down the side of the beaker to get 2 layers. Try not to agitate the interface.
- With the hooked spatula, grasp the polymer film at the interface and pull up from the center of the beaker.
- Wrap the polymer thread around the stirring rod.
- Continue to spool the thread around the stirring rod by slowly turning the stirring rod.
- Wash the nylon thoroughly with water before handling.
Discussion:
N/A
Hazards:
Hexane is flammable, so keep this away from open flames and ignition sources. Solution 1 is basic, so if any comes in contact with skin, wash with copious water.
SOP: 
Acutely Toxic – Sebacoyl Chloride
Carcinogen – Hexane
Corrosive – Sodium Hydroxide
Reproductive Hazard – Hexane,
Disposal (by Storeroom)
Thoroughly mix the remaining solution and remove any solid nylon that is produced. Wash the nylon and discard in a solid waste container. Discard remaining liquid in a solvent waste container.
