Abstract
The interaction between tetraethylammonium chloride (TEACl) with ICl and tetraethylammonium iodide (TEAI) and aza-15-crown-5 (A15C5) with $I_2$ and ICl have been examined spectrophotometrically in acetonitrile solution. The results of TEACl-ICl indicate the formation of $ICl_2$ - through equilibrium reaction. In the case of TEAI-$I_2$ and A15C5-$I_2$, the equilibrium formation of $I_3$ - is confirmed. The interaction of TEAI-ICl begins with the simultaneous production of $I_2$ and IC$I_2$ - (at TEAI/ICl < 0.5) as well as continues with the simultaneous consumption of $I_2$ and formation of I$I_3$ - (at TEAI/ICl > 0.5). Similar behavior is also observed for A15C5-ICl system. However, the changes are seen at A15C5/ICl mole ratios less and more than 0.66. Several equations have been suggested for the formation of detected species. The formation constants of various reactions were evaluated from the computer fitting of the absorbance-mole ratio data. IR spectra of A15C5 and 1:1 A15C5:ICl or A15C5:$I_2$ complexes are compared and the effect of complexation on absorption bands is discussed.
