Adipic acid composition determined by IR spectroscopy

Abstract
In this article, we determined the composition
of adipic acid using IR spectroscopy and the Nicolet-Magna 550 IR spectrometer
as the instrument. Adipic acid has the formula (CH2)4(COOH)2
and contains the following functional groups: C=O, C-H, CH2. Adipic
acid (also called hexanedioic acid) is a dicarboxylic organic compound,
characterized by the molecular formula C₆H₁₀O₄ and the linear structure
of the aliphatic chain. The molecule contains two carboxyl groups (-COOH)
located at the ends of a chain of six carbon atoms, separated by four methylene
units (-CH₂-). This
architecture gives adipic acid moderate acidic properties, high thermal
stability and versatility in polycondensation reactions. Due to its symmetry
and chain flexibility, adipic acid is an essential precursor in the synthesis
of polymers, especially nylon-6,6 polyamides, as well as in various industrial
applications where a well-defined dicarboxylation is required.
