Answer 2

$\huge\red{\boxed{\bold{Answer}}}$

How is nylon - 66 synthesized?

Ans: Nylon -6,6 is synthesized by polycondensation of hexamethylenediamine and adipic acid. Equivalent amounts of hexamethylenediamine and adipic acid are combined with water in a reactor.

This is crystallized to make nylon salt, an ammonium/carboxylate mixture.

Thus molten nylon 66 is formed.
