Interaction Study of Some Ortho and Para Amines With 1-Octanol

Molecular interaction between Ortho and Para amines such as Chloroaniline, Methylaniline, and Methoxyaniline with 1-Octanol has been studied in carbon tetrachloride by using FT-IR study. The most likely association complex between 1-octanol and subsistent of aniline is 1:1 stoichiometric complex through hydroxyl group of 1-octanol and amines group of ortho and para subsistent of anilines. As donor's concentration increases, the formation of complex is also increases. Interactions are studied for 1:1 complex on the bases of formation constant and free energy changes. Formation constant of the complex has been calculated using Nash method. The results shows, formation constant obtained are agreed to a reasonable extent. The ability of acceptors is in the order of P-Cholroaniline<O-Chloroaniline< O-Methylaniline<O-Methoxyaniline<P-Methoxyaniline<P-Methylaniline. The results shows that interacting molecules of 1-octanol as protons donor with methyl and chloride substitution of amines in ortho position is smaller than the para position substitution of amines.
