Polymers: Synthesis of Nylon by
Interfacial Polymerization
Purpose
• In this experiment a 10-carbon diacid is converted to
the corresponding diacid chloride with thionyl
chloride. The diacid chloride product is then reacted
with 6-carbon diamine in a biphasic system. Where
the solutions come in contact, nylon 6.10 is formed.
Comments
• Follow pp. 818-820 (microscale).
• Follow the lab handout for all experimental
procedures. Wearing rubber gloves is
necessary during this lab. You will work with
toxic and corrosive compounds.
• Calculate yield. Moderate to good yields
should be achieved.

Safety
• 1,6-Hexanediamine is harmful by contact with skin
and if swallowed and causes burns. Also is irritating
to respiratory system. Do not swallow and inhale
dust. Wear gloves and eye protection. In case of
contact with eyes, rinse immediately with plenty of
water and seek medical advice.
• Thionyl chloride is harmful by inhalation and if
swallowed; causes severe burns. Contact with water
liberates toxic gas (SO2). Do not swallow, do not
inhale and avoid contact with eyes and skin. Wear
protective gloves and goggles.
