Solid acid catalysts are extensively used in a number of industrially important catalytic reactions. Here, water-insoluble novel mesoporous solid acid catalysts, with a unique structure composed of WOx nanorods and W nanoballs within an amorphous silicate lattice, were synthesized following a one-pot hydrothermal route. using silicotungstic acid (STA) as the active component. Surface area of these catalysts ire more than 2 orders of magnitude higher than that of pure STA, and they showed very high activity for the simultaneous production of ethylene and diethylether (DEE), which is an attractive transportation fuel alternate, from a nonpetroleum feedstock, namely ethanol. Depending upon the operating conditions, ethylene or DEE selectivities approaching 1 0 or 0 8 were obtained, respectively.

Novel conversion of thiols into disulfides, via S-nitrosothiol intermediates using trichloronitromethane Demir, Ayhan Sıtkı; Igdir, AC; Mahasneh, AS (1999-10-15) An efficient oxidative coupling of thiols to give disulfides via thionitrite (S-nitrosothiol) intermediate is described using trichloronitromethane as an efficient reagent in organic solvents and water. Cysteine and glutathione are converted into the corresponding disulfides in water in high yields.
Direct synthesis of hydrogen storage alloys from their oxides Tan, Serdar; Öztürk, Tayfur; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2011) The aim of this study is the synthesis of hydrogen storage compounds by electrodeoxidation technique which offers an inexpensive and rapid route to synthesize compounds from oxide mixtures. Within the scope of this study, two hydrogen storage compounds, FeTi and Mg2Ni, are aimed to be produced by this technique. In the first part, effect of sintering conditions on synthesis of FeTi was studied. For this purpose, oxide pellets made out of Fe2O3-TiO2 powders were sintered at temperatures between 900 °C – 1300...
Studies towards green oxidation of alcohols with visible light Akkaş, Kıvanç; Akdağ, Akın; Department of Chemistry (2014) Conversion of alcohols to the corresponding carbonyl compounds is one of the key reactions in organic chemistry. For this, numerous methods have been developed. However, most of these methods produce environmentally hazardous waste. With this in mind, an environmentally benign method was attempted to be developed. The idea was borrowed from Dye Sensitized Solar Cells (DSSC); electron relay mechanism in DSSC to be replaced with oxidation of alcohols. First, TiO2 as metal oxide and O2 as electron acceptor wer...
Synthesis and characterization of polycaprolactone-based segmented polyurethanes Guney, Aysun; Kızıltay, Aysel; Hasırcı, Nesrin; Endoğan Tanır, Tuğba (2019-01-01) Segmented polyurethanes were synthesized by the reactions of poly(epsilon-caprolactone) (PCL)-diol and 1,6-hexamethylene diisocyanate through bulk polymerization without using solvent, initiator, or catalyst. Phase separation and hydrogen bond formation between hard segments or between hard and soft segments were examined by Fourier transform infrared spectroscopy (FTIR)-ATR and X-ray diffraction (XRD), while physical and mechanical properties were studied by atomic force microscope, differential scanning c...
Synthesis of new mediators for electrochemical nad/nadh recycling Khalily, Mohammad Aref; Demir, Ayhan Sıtkı; Department of Chemistry (2011) The synthesis of enantiopure compounds can be achieved by using dehydrogenases as biocatalysts. For instance, reduction reactions of prochiral compounds (ketones, aldehydes and nitriles) into chiral compounds can be achieved by dehydrogenases. These dehydrogenases are cofactor dependent where cofactor is Nicotinamide Adenin Dinucleotite having some restrictions that confines usage of dehydrogenases in organic synthesis including instability of cofactor in water and high cost. Therefore, suitable recycling m...
