Question

Nylon 6,6 may be formed by means of a condensation polymerization reaction in which hexamethylene diamine [NH2-(CH2)6-NH2] and adipic acid react with one another with the formation of water as a byproduct. What masses of________(a) hexamethylene diamine and(b) adipic acid are necessary to yield 26 kg of completely linear nylon 6,6? This polymerization reaction occurs according to the following equation:

Answer 1

Answer:

Mass of hexamethylenediamine= 13,470.62 g

Mass of adipic acid =  16,940.13 g

Explanation:

Nylon -6,6 is synthesized by poly-condensation of hexamethylenediamine [NH₂-(CH₂)₆-NH₂] and adipic acid (C₆H₁₀O₄).

Both of these are taken in equal equivalents and reacted to form nylon 6,6 and by-product water is also formed.

Molecular mass of hexamethylenediamine [NH₂-(CH₂)₆-NH₂] =116.21 g/mol

Molecular mass of adipic acid (C₆H₁₀O₄) = 146.1412 g/mol

Molecular mass of Nylon 6,6 (C₁₂H₂₀N₂O₂) = 224.3 g/mol

Using unitary method :

Mass of hexamethylenediamine required for 26,000 g of Nylon 6,6 if 116.21 g/mol is required for 224.3 g/mol, is:

= $\frac{26,000 *  116.21}{224.3}$

= 13,470.62 g

Mass of adipic acid required for 26,000 g of Nylon 6,6 if 146.1412 g/mol is required for 224.3 g/mol, is:

= $\frac{26,000 *  146.1412}{224.3}$

= 16,940.13 g
