Question
Which is used in the formation of nylon-6,6?
- Sulphur hexafluoride
- Adipic acid
- Sulphurous acid
- Phthalic acid
Solution
Adipic acid is used in the formation of nylon-6,6.
Here are the steps of how nylon-6,6 is formed:
-
Adipic acid and hexamethylenediamine are the two main ingredients used in the formation of nylon-6,6.
-
These two compounds undergo a condensation polymerization reaction. In this process, two molecules combine and lose small molecules as byproducts such as water or methanol.
-
The carboxyl group of adipic acid reacts with the amine group of hexamethylenediamine, resulting in the formation of an amide group, which is the characteristic group in nylon.
-
This reaction is repeated multiple times, forming a long chain polymer, which is nylon-6,6.
-
The number 6,6 represents the number of carbon atoms in the adipic acid and hexamethylenediamine monomers, respectively.
