Experiment: Synthesis of Nylon 6,6

Objective: To demonstrate the synthesis of Nylon 6,6, a polyamide used in textiles, carpets, and engineering plastics. This experiment illustrates a condensation polymerization reaction.

Materials:

  • Hexamethylene diamine (HMD) - 10g
  • Adipoyl chloride (AC) - 12g
  • Sodium hydroxide (NaOH) solution (10%, for neutralizing any excess acid. Amount will depend on the scale of the experiment.)
  • Water (distilled water is recommended)
  • 2 Beakers (250mL or larger)
  • Stirring rod
  • Graduated cylinder (for accurate measurement of liquids)
  • Funnel
  • Filter paper
  • Thermometer
  • Hot plate or Bunsen burner (with appropriate safety precautions)
  • Safety goggles and gloves

Procedure:

  1. Dissolve 10 g of HMD in 50 mL of water in a beaker. Stir until completely dissolved.
  2. In a separate beaker, dissolve 12 g of AC in 50 mL of water. Stir until dissolved. This step should be done in a fume hood due to the irritating nature of adipoyl chloride.
  3. Slowly add the AC solution to the HMD solution while stirring vigorously using the stirring rod. The reaction will occur at the interface of the two solutions. You will observe the formation of a continuous strand of nylon that can be drawn out using forceps or tweezers.
  4. Continue stirring gently. The nylon will form a solid mass at the interface and can be slowly pulled out.
  5. Once a significant amount of nylon has formed, carefully remove the nylon from the solution and wash the nylon fiber with the dilute NaOH solution and then with plenty of water to remove any remaining reactants.
  6. (Optional) For a cleaner product, the nylon can be further purified by washing with a suitable organic solvent such as ethanol, followed by drying.
  7. Dry the nylon in air or in an oven at a low temperature (around 80-90°C) to remove any remaining water.

Observations:

  • Formation of a continuous, white, fibrous nylon polymer at the interface between the two solutions.
  • The nylon fiber is strong and can be drawn into long strands.
  • The washed nylon is a white, fibrous solid.

Safety Precautions: Adipoyl chloride is an irritant. This experiment should be performed in a well-ventilated area or fume hood. Wear safety goggles and gloves throughout the experiment. Handle all chemicals with care.

Significance:

This experiment demonstrates the synthesis of Nylon 6,6, a polyamide with a wide range of industrial applications. Polyamides are characterized by their high strength, toughness, and durability, making them suitable for use in textiles, carpets, engineering plastics, and other products. The process showcases a condensation polymerization, a crucial reaction type in polymer chemistry.
