Naylon 6,10 Yapımı (Naylon İp Hilesi)

İki faz ara yüzeyinden sürekli naylon ipliği çekme

Organic Synthesis Intermediate (High School) 30 dak ~$18,00

Hedef

Birbiriyle karışmayan iki çözeltinin ara yüzeyinde naylon 6,10 sentezlemek ve beherden sürekli bir iplik çekmek.

Arka Plan

The nylon rope trick is a dramatic demonstration of interfacial polymerization. When a solution of hexamethylenediamine (aqueous) is layered with sebacoyl chloride (in hexane), nylon forms at the interface. The polymer film can be continuously pulled out as a thread or rope.

Güvenlik Uyarıları

  • Hexane is highly flammable — no open flames
  • Sebacoyl chloride is corrosive and moisture-sensitive
  • Hexamethylenediamine is an irritant
  • Work in a fume hood

Malzemeler

  • Hexamethylenediamine (3 g)
    Dissolved in 50 mL water
  • Sebacoyl chloride (2 mL)
    In 50 mL hexane
  • Sodium hydroxide (NaOH) (1 g)
    Added to the aqueous layer
  • Hexane (50 mL)

Ekipman

250 mL beaker Forceps or glass rod Paper towel

Prosedür

1

Prepare the aqueous solution: dissolve 3 g hexamethylenediamine and 1 g NaOH in 50 mL water in the beaker.

3 dak Irritant — avoid contact
2

Carefully layer the sebacoyl chloride/hexane solution on top of the aqueous solution. Do not mix.

5

Wind the nylon strand around a glass rod, continuously pulling from the interface.

Beklenen Sonuçlar

A continuous strand of nylon can be pulled from the interface for several meters. The polymer is white, slightly elastic, and strong. The reaction continues as long as both reagents are present.

Temizlik

Allow remaining solution to react. Dispose of hexane waste in organic solvent waste. Neutralize the aqueous layer. Rinse all glassware.
