Title: Nylon 6,6 sythesis: reagents theoretical quantity
Post by: Mimic on June 19, 2022, 02:22:32 PM

This is the nylon 6,6 reaction

Having these data available, I would need to know the theoretical quantities, in grams, of the monomers

My attempt:
Adipoyl chloride is our limiting reactant so theoretical mass is the weighted mass.
Hexamethylenediamine and adipoyl chloride are in 1:1 ratio, so amine theoretical mol are the same of adipoyl chloride: if the calculations are correct, [itex]0.0022\;\text{mol}[/itex].
From which, the theoretical mass of amine will be

[tex] 0.0022\;\text{mol} \times 116.21\;\text{g/mol} = 0.2557\;\text{g}[/tex]

Any advice?

Its not clear what your question is. I follow your work so far and don't take any issue with it.

I just want to know if my attempt is correct  :)

I'm asking you "What is the question the assignments is asking?"


But reading between the lines, yes I think you did the assignment correctly.
