Sodium, ammonium, calcium, and magnesium forms of zeolite Y for the adsorption of glucose and fructose from aqueous solutions Heper, Misket; Türker, Burhan Lemi; Kincal, N. Suzan (Elsevier BV, 2007-02-01) The kinetics of adsorption by sodium, ammonium, calcium and magnesium forms of zeolite Y from aqueous solutions containing 25% w/v of either one or an equimolar mixture of glucose (G) and fructose (F) have been studied batch-wise at 50 degrees C. The adsorption of aqueous pure G was fast, while that of aqueous pure F depended on the cationic form, approaching that of G on the Mg-Y, and slowing down in the sequence of Mg2+ > NH4+ > Ca-2(+) > Na+ of the cations. The adsorption behavior from solutions containi...
SODIUM, RUBIDIUM AND CESIUM UPTAKE ON LOS-TRANCOS CLAY GOKTURK, H; DYER, A (Springer Science and Business Media LLC, 1994-10-03) The uptake of sodium, caesium and rubidium onto Los Trances clay was studied using the batch method. Sodium-22, rubidium-86 and caesium-137 were used as tracers. In most of the experiments cation concentrations used were 0.01 N. Triple distilled and deionized water ware used and the grain size of all solid particles was less than or equal to 53 mu m. In all cases a few hours of shaking was enough to reach the equilibrium. The ion exchange isotherm experiments were performed by using ammonium forms of the cl...
Potassium permanganate/ carboxylic acid/ organic solvent: a powerful reagent for c-c bond formation, aryl coupling reactions and enone oxidation ipso-nitration of arylboronic acids with silver nitrite/ tmscl Fındık, Hamide; Demir, Ayhan Sıtkı; Department of Chemistry (2009) The first part of the thesis presents the KMnO4/ carboxylic acid/ organic solvent which is a powerful reagent for C-C bond formation, aryl coupling reactions and enone oxidation. The a¢-acetoxylation of enones and the a-acetoxylation of aromatic ketones were carried out with potassium permanganate and acetic acid, in which acetoxylation products were obtained in 74-96% yields. The same reaction was carried out with carboxylic acids other than acetic acid, which furnished corresponding acyloxy ketones with t...
Magnesium substituted cobalt spinel nanostructures for electrocatalytic water oxidation Ekebas, Elif; Çetin, Asude; Önal, Ahmet Muhtar; Nalbant Esentürk, Emren (Springer Science and Business Media LLC, 2019-03-01) Two MgCo2O4 nanostructures in different morphologies have been synthesized by using two different structure-directing agents (urea (U) and nitrilotriacetic acid (NTA)) as new catalysts for water oxidation reactions. The properties of these nanostructures were discovered and characterized by a combination of analytical techniques, being TEM, SEM, EDX, XRD, XPS, and BET. While the urea-stabilized MgCo2O4 (U-MgCo2O4) nanostructures have spiky morphology, the NTA-stabilized ones (NTA-MgCo2O4) have wire-like str...
Potassium permanganate/carboxylic acid/organic solvent: a powerful reagent for enone oxidation and aryl coupling reactions Demir, Ayhan Gürbüz (2008-06-30) The alpha'-acetoxylation of enones and the alpha-acetoxylation of aromatic ketones were carried out with potassium permanganate and acetic acid, in which acetoxylation products were obtained in 74-96% yields. The same reaction was carried out with carboxylic acids other than acetic acid, which furnished corresponding acyloxy ketones with the same regioselectivity. For the first time, formyloxylation products were synthesized in a 61-85% yield by using formic acid. The potassium permanganate and acetic acid ...
