Solubility of Iodine in Glycol-Water Solutions*

The Properties of Iodine in Solutions of Surface-Active Agents ,

“…3, the comparison between the visible spectra of iodine in water, heptane, polyethylene glycol 600, and Antarox indicates that this compound is solubilized by association with the polyethylene glycol portion of the Antarox molecule. The ultraviolet spectrum is also in agreement with the above conclusion and the absorption maxima observed are in agreement with those reported by Osol (32). Besides the acid-base association with polyethylene glycol (32), iodine reacts chemically in such a manner that solubilization properties for iodine are partially destroyed.…”

Tailoring lixiviant properties to optimise selectivity in E-waste recycling

“…27 The presence of water or different ethylene glycol content may affect the formation of these species, as the solubility of iodine in ethylene glycol is 0.28 mol dm −3 , whereas the solubility in water is only 1.32 × 10 −3 mol dm −3 when no additional complexing agents are present. 43 Therefore, extended X-ray absorption fine structure (EXAFS) spectroscopy was carried at the iodine K-edge out on samples containing nominally 0.1 mol kg −1 iodine, with the DES containing a range of water contents up to 20 wt%, and also for four different molar ratios of EG : ChCl.…”

Understanding the Crystal Growth of Bismuth Chalcohalide Nanorods through a Self-Sacrificing Template Process: A Comprehensive Study

“…Molecular iodine is a nonpolar molecule that has different interactions with different solvents. Literature reports place the interaction of solvents such as MEG and I 2 as a charge-transfer type, where MEG acts as a coordinating solvent, producing a brown solution, unlike solvents such as water in which the solution is violet. In this interaction, I 2 can take an electron from MEG, in the equilibrium thus achieving the desired −1 oxidation state needed for BiSI …”
