Chapter 31: Q24E (page 1054)

Nomex, a polyamide used in such applications as fire-retardant clothing, is prepared by reaction of 1,3-benzenediamine with 1,3-benzenedicarbonyl chloride. Show the structure of Nomex.

Short Answer

Expert verified

Nomex is used as a fire-retardant.

It is prepared by polymerization of 1, 3-benzenediamine, and 1, 3-benzenedicarbonyl chloride. The physical properties include high tensile strength and high temperature.

Step by step solution

01

Step-by-Step Solution

Nomex is used as a fire-retardant.

It is prepared by polymerization of 1, 3-benzenediamine, and 1, 3-benzenedicarbonyl chloride. The physical properties include high tensile strength and high temperature.

02

Mechanism of the reaction

In the given reaction the hydrogen of 1, 3 benzenediamine and chlorine of 1, 3 benzene dicarbonyl chloride is removed as a HCl molecule and we get Nomex as a polymer.

The mechanism of the reaction is as follows;
