Nylon 6-10 Preparation kit

Quick Answer: The nylon 6-10 preparation kit is used to make nylon 6,10, a polyamide, by reacting a six-carbon diamine with a ten-carbon diacid chloride at the boundary of two immiscible liquids. The name of the polymer records those two carbon counts, which makes it a useful case study in how polymers are named.

What the Numbers 6 and 10 Mean

Nylons are polyamides, chains whose units are joined by amide links. When a nylon is made from two different monomers, its name gives the number of carbon atoms in each. Nylon 6,10 comes from hexane-1,6-diamine, with six carbons, and decanedioyl dichloride, the acid chloride of sebacic acid, with ten. Nylon 6,6, the common textile polymer, uses a six-carbon diacid instead.

In the reaction the diamine is dissolved in water, often with a little alkali to neutralise the acid produced, and the acid chloride in a water-immiscible solvent. At the boundary the two react so quickly that a skin of nylon 6,10 forms immediately. Gripping that skin with tweezers and lifting draws out a continuous rope, which can be wound onto a glass rod.

Acid chlorides react far faster than the acids themselves, which is why this reaction works at room temperature while industrial nylon production needs heat. For a class in which each group makes its own thread, the nylon synthesis kit for students is titled for that purpose; this kit is titled for nylon 6,10 specifically.

Applications

• Teaching polymer naming, with nylon 6,10 and nylon 6,6 as a comparison
• Demonstrating the amide link and condensation polymerisation in senior secondary or first-year college chemistry
• Winding the product onto a glass rod to estimate how much polymer forms from a set volume of reagent
• Comparing a synthetic polyamide with a natural one such as silk

Care & Handling

• Handle the acid chloride solution in a fume cupboard; it fumes in moist air and releases hydrogen chloride.
• Wear goggles and chemical-resistant gloves when dispensing either monomer.
• Wash the finished rope thoroughly in running water before it is passed round the class.
• Keep the reagent containers tightly closed and away from moisture, and check dates before use, as acid chlorides degrade on contact with water vapour.

Why Choose LabEquip

College and upper-secondary chemistry teachers covering polymers and nomenclature use a nylon 6,10 preparation to link a named polymer to its monomers. LabEquip lists this kit under chemistry lab equipment; questions about reagent quantities can be sent through the contact page.

Frequently Asked Questions

Why is it called nylon 6,10?

The first number is the number of carbon atoms in the diamine monomer and the second is the number in the diacid monomer. Nylon 6,10 is made from a six-carbon diamine and a ten-carbon diacid chloride.

Why use an acid chloride instead of the carboxylic acid?

An acid chloride reacts with an amine rapidly at room temperature. The dicarboxylic acid itself would need prolonged heating to form amide links, which is impractical in a classroom and would not give the continuous rope effect.

What is the small molecule lost in the reaction?

Hydrogen chloride. It is released as each amide link forms, which is why alkali is often added to the aqueous layer to neutralise it.

How is nylon 6,10 different from nylon 6,6?

Both are polyamides. Nylon 6,6 uses a six-carbon diacid, so its amide groups are closer together than in nylon 6,10. Nylon 6,10 absorbs less water, which affects properties such as flexibility in damp conditions.

Does the kit need a fume cupboard?

One is strongly recommended for dispensing the acid chloride, which gives off hydrogen chloride in moist air, and the organic solvent is volatile. Drawing the rope itself can be shown on an open bench with good ventilation.

How should leftover reagents be treated?

Stir the remaining layers together so the monomers react to form solid nylon, which can be lifted out. Dispose of the liquids as your safety data sheets and local rules direct, not down the sink.
