Phase diagram of an iodine-Potassium Iodide-water-ethanol system at 25°C
Russian Journal of Physical Chemistry A, 2012Co-Authors: T. M. Varlamova, E. M. Rubtsova, S. P. MushtakovaAbstract:Phase equilibriums are studied in the isothermal-isobaric sections of the phase diagram of a fourcomponent iodine-Potassium Iodide-water-ethanol system at 25°C and atmospheric pressure. The compositions of the solvent at which it exhibits the greatest ability to dissolve iodine are established. It is shown that in all the investigated sections, there is three-phase eutonic equilibrium with Potassium Iodide and crystalline iodine as the solid phases. It is revealed that in the sections containing 30 and 50% of ethanol, Potassium Iodide serves as the salting in agent for crystalline iodine, due to the formation of polyIodide complexes of various composition in the studied system.

Solubility diagrams of the Potassium Iodide-water-ethanol and iodine-water-ethanol ternary systems
Russian Journal of Physical Chemistry A, 2009Co-Authors: T. M. Varlamova, E. M. Rubtsova, S. P. MushtakovaAbstract:The solubility of Potassium Iodide and iodine in water-methanol mixed solvents was studied by the method of sections at 25°C and atmospheric pressure. The solubility of Potassium Iodide was found to decrease as the content of ethanol in aqueous-alcoholic solutions increased. The solubility of crystalline iodine had a complex dependence on mixed solvent composition; it was maximum in mixtures containing 90 wt % alcohol. The compositions of the solid phases that crystallized in the KI-H2O-C2H5OH and I2-H2O-C2H5OH systems were substantiated by X-ray measurements.

Phase equilibria in the iodine-Potassium Iodide-water-propanol-2 four-component system
Russian Journal of Physical Chemistry A, 2008Co-Authors: G. V. Gerasimova, T. M. Varlamova, S. P. MushtakovaAbstract:Isothermal-isobaric sections of the phase diagram of the iodine-Potassium Iodide-water-propanol-2 (2-C3H7OH) four-component system were studied at 25°C and atmospheric pressure. In all sections, threephase eutonic equilibria were observed with Potassium Iodide and crystalline iodine as solid phases. Potassium Iodide was a iodine salting in agent in sections containing 15 and 25 wt % propanol-2 and a salting out agent in the section with 50 wt % alcohol. H2O-2-C3H7OH (85: 15 and 75: 25 wt %) mixed solvent compositions showed a higher ability to dissolve iodine than mixture components.

clinical evaluation of diamine silver fluoride Potassium Iodide as a dentine desensitizing agent a pilot study
Australian Dental Journal, 2012Co-Authors: Graham G Craig, G M Knight, J M McintyreAbstract:Background: The aim of the present study was to compare the efficacy of an experimental diamine silver fluoride/Potassium Iodide product with an oxalic acid-based preparation in reducing dentine hypersensitivity. Methods: The study was conducted as a double-blind, randomized clinical trial. A total of 19 subjects with dentine hypersensitivity on both sides of their upper arch were selected. The most sensitive tooth in each quadrant was identified and received a cold stimulus. The response was recorded on a visual analogue scale (VAS). The tooth thus selected was treated with one of the treatment agents. One week later the level of dentine sensitivity was assessed. Participants were also asked for their subjective assessment of treatment effects. Results: The mean difference between VAS at baseline and seven days for teeth treated with diamine silver fluoride/Potassium Iodide was greater than that for teeth treated with the oxalic acid-based preparation (p = 0.0134). The subjects’ subjective assessment of changes in dentine hypersensitivity indicated that more obtained relief with the diamine silver fluoride/Potassium Iodide treatment (p = 0.0129). Conclusions: It was concluded that an experimental diamine silver fluoride/Potassium Iodide product has potential as a treatment for dentine hypersensitivity.
