Exploring Diverse Interactions of Some Surface-Active Ionic Liquids with Amino Acids Prevalent in Aqueous Environments by Physicochemical Contrivance: Experimental investigation | Chapter 2| Progress in Chemical Science Research Vol. 2

 With two (ILS) [BMIM] [C8SO4] and [MOIM] Cl and amino acids (AA) (AA = L-tyr, L-phe) using molar conductivity (Ʌ) at three different temperatures. I studied the molecular interaction of. .. In an aqueous medium. Spectroscopic experiments were performed to study the behavior of IL and  selected amino acids, and the spontaneity of the process. Amino acids are a component of proteins and are therefore used as model compounds.  Changes in the electronic states of different protons of IL in the presence of different amino acids were also verified by 1H NMR spectroscopy. Order  ([BMIM] [C8SO4] + L-tyr)> ([MOIM] Cl + L-tyr)> ([BMIM] [C8SO4]  + L-phe)> ([MOIM] Cl + L-phe) Used to interpret all  data in water in terms of possible molecular interactions. The experimental parameters obtained are very helpful in understanding the mixing effects and other complex biological processes that occur between amino acids and selected ionic liquids. Significant chemical shifts of ILs protons in the presence of amino acids in 1H NMR study  also  support  results obtained from other spectroscopic and conductivity measurements

Ion Association Constants and Calculation of Thermodynamic Parameters of N-[(benzoyl-amino) thioxomethyl] Serine Copper (II) Chloride in Methanol + Water Mixed Solvents | Chapter 9 | Challenges and Advances in Chemical Science Vol. 7

 Conductance values of a complex, N-[(benzoyl-amino) thioxomethyl] serine copper (II) chloride was estimated in methanol-water mixed solvents, viz.,  Xmethanol =0.0000 – 1.0000 at temperature ranges

283.15 to 313.15 K. From the experimental results, the ion association constants (KA) and limiting equivalent conductance (^0)  were determined by analyzing conductivity data concerning Shedlovsky
equations for the electrolytes. The Walden product, (^0Ƞ0) values were calculated in various water + + methanol mixtures at 283.15 to 313.15 K .It was observed that the increase in the percentage of values were calculated in various water methanol mixtures at to . It was observed that the increase in the percentage of methanol results in an increase in association constant values. It was also found that with the increase in KA values dielectric constant values were also increased. Increase in KA values with the increase in the dielectric constants of the mixtures. ^0  values linearly increased as the increased in temperature. Thermodynamic factors were calculated from the KAs and the results we got were examined.
