二液界面でナイロン6,10を合成し、ビーカーから連続した糸を引き出す。

背景

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.

安全上の警告

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

必要なPPE

材料

  • 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

器具

250 mL beaker Forceps or glass rod Paper towel

手順

1

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

3 分 Irritant — avoid contact
2

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

3 分 Work in fume hood
3

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

2 分
4

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

5 分
5

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

10 分
6

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

5 分

予想される結果

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.

後片付け

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