नायलॉन 6,10 बनाना (नायलॉन रस्सी ट्रिक)

इंटरफेस से नायलॉन की एक निरंतर डोर खींचना

Organic Synthesis Intermediate (High School) 30 मिनट ~$18.00

उद्देश्य

दो अमिश्रणीय विलयनों के इंटरफेस पर नायलॉन 6,10 का संश्लेषण करें और बीकर से एक निरंतर डोर खींचें।

पृष्ठभूमि

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.

सुरक्षा चेतावनियाँ

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

आवश्यक PPE

goggles gloves lab_coat

सामग्री

  • 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)
    Solvent for acid chloride

उपकरण

250 mL beaker Forceps or glass rod Paper towel

प्रक्रिया

1

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

3 मिनट Irritant — avoid contact
2

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

3 मिनट Work in fume hood
3

Observe the nylon film forming at the interface between the two layers.

2 मिनट
4

Using forceps, gently pull the nylon film from the center of the interface. A continuous strand should follow.

5 मिनट
5

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

10 मिनट
6

Rinse the collected nylon with water and blot dry. Examine the fiber properties.

5 मिनट

अपेक्षित परिणाम

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.

सफाई

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