Synthesis, potentiometric titrations and antioxidant activities of some 4-acylamino-4,5-dihydro-1H-1,2,4-triazol-5-one derivatives
(2008)
Five novel 3-alkyl-4-cinnamoylamino-4,5-dihydro-1H-1,2,4-triazol-5-ones (2) were synthesized by the reactions of 3-alkyl-4-amino-4,5-dihydro-1H-1,2,4- triazol-5-ones (1) with cinnamoyl chloride and characterized by elemental ...
The microwave-assisted synthesis and characterization of novel polymeric phthalocyanines containing resorcinarene
(Elsevier, 2008)
Novel metal phthalocyanine (Cu, Zn, Co, Ni) polymers containing resorcinarene moieties were prepared; the resorcinarene was obtained by the acid-catalysed cyclocondensation of resorcinol and acetaldehyde under microwave ...
Performance of magnesium oxide-coated bentonite in removal process of copper ions from aqueous solution
(Elsevier, 2010)
This paper presents the adsorption of Cu(II) ions from aqueous solution on modified Unye bentonite. Adsorption of Cu(II) ions by magnesium oxide-coated bentonite (MCB) sample was investigated as a function of the initial ...
Novel phthalocyanines containing substituted salicyclic hydrazone-1,3-thiazole moieties: Microwave-assisted synthesis, spectroscopic characterization, X-ray structure and thermal characterization
(Elsevier, 2010)
Novel, metal-free and metallo(Cu, Co, Ni, Zn, Pb and Mn)phthalocyanine compounds were synthesized by exposure to microwave irradiation and the products purified. The newly prepared compounds were characterized using elemental ...
Determination of the protonation constants of triazole derivatives in non-aqueous solvents
(2009)
Different 17 triazole derivatives were titrated with tetrabutylammonium hydroxide in four non-aqueous solvents (isopropyl alcohol, rert-butyl alcohol, N,N-dimethylformamide and acetonitrile), using Potentiometric method. ...
Structural analysis of reactive dye species retained by the basic alumina surface
(2009)
The alumina-dye composites were prepared by treating the basic alumina with the water solutions of Reactive Red 120 (RR 120) and Reactive Blue 15 (RB 15) dyes. The bands of low intensities in the 1400-1600 cm-1 region and ...
The microwave-assisted synthesis and characterization of novel, octakis(2-hydroxyethoxy)resorcinarene bridged polymeric metallophthalocyanines
(Elsevier, 2009)
The new metallophthalocyanine (Zn, Cu, Ni, Co) polymers containing 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)-2,8,14,20-tetramethylresorcinarene are described. Firstly, 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)- ...
Synthesis of methyl (E)-2′,4″-thiazachalcones and their N-alkyl derivatives, photochemistry with theoretical calculations and antimicrobial activities
(TUBİTAK, 2009)
A series of 9 new (E) -thiazachalcones (1-3), and their N -alkyl substituted derivatives (4-6), and stereoselective dimerization products (7-9) were synthesized, then tested for antimicrobial activity against all test ...
Determination of adsorptive properties of a Turkish Sepiolite for removal of Reactive Blue 15 anionic dye from aqueous solutions
(Elsevier, 2009)
Reactive Blue 15 (RB 15) adsorption on the Turkish Sepiolite was carried out by batch equilibrium technique. IR spectrum and surface area measurement of the composite of dye-sepiolite (Turkish) pointed out that dye species ...
Reversible immobilization of catalase by using a novel bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents
(Elsevier, 2008)
This study focused on developing bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents (38-105 ?m) for catalase adsorption from aqueous solutions. Pseudo-biospecific affinity ligand l-cysteine was covalently binded ...
