    Required Training

    Required PPE

    UC Lab Safety Fundamentals

    Lab coat, safety glasses/goggles, nitrile gloves

    Equipment

    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:

    1. Wearing gloves, place Solution 1 in the beaker. Food coloring can be added to this layer to enhance visibility of the interface.
    2. Slowly pour Solution 2 down the side of the beaker to get 2 layers. Try not to agitate the interface.
    3. With the hooked spatula, grasp the polymer film at the interface and pull up from the center of the beaker.
    4. Wrap the polymer thread around the stirring rod.
    5. Continue to spool the thread around the stirring rod by slowly turning the stirring rod.
    6. Wash the nylon thoroughly with water before handling.

    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.

    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.
