Abstract:
Acetone and n-pentane from an azeotrope with the mole ratio of 1:3, respectively. As the result of this azeotrope formation, some characteristic vibrational modes in FT-IR and chemical shifts in 1H NMR changes. The amount of these band and signal changes is an indication of the extend of interaction between two components and their orientation in unit structure of the cluster. FT-IR and 1H NMR spectra of pure substances and their azeotrope were recorded, spectral changes analyzed. Unit structure of azeotrope was deduced based on mole ratio, boiling point changes of pure components, and spectral changes in fundamental frequency and chemical shifts.
