In this study, two new pyrazolium based tunable aryl alkyl ionic liquids, 2-ethyl-1-(4-methylphenyl)-3,5- dimethylpyrazolium tetrafluoroborate (3a) and 1-(4-methylphenyl)-2-pentyl-3,5-dimethylpyrazolium tetrafluoroborate (3b), were synthesized via three-step reaction and characterized. The removal of methylene blue (MB) from aqueous solution has been investigated using the synthesized salts as an extractant and methylene chloride as a solvent. The obtained results show that MB was extracted from aqueous solution with high extraction efficiency up to 87 % at room temperature at the natural pH of MB solution. The influence of the alkyl chain length on the properties of the salts and their extraction efficiency of MB was investigated.

Synthesis of New Thienylene Pyrrole Monomers and Their Electropolymerizations
Eken, Serap; Carbas, Buket Bezgin; Akdağ, Akın; Önal, Ahmet Muhtar (The Electrochemical Society, 2014-01-01)
In this study, four new 2,5-dithienylpyrroles (SNS) 1-(3-fluoro-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-FPTP), 1-(3-chlorophenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-ClPTP), 1-(3-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-BrPTP) and 1-(4-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (p-BrPTP) containing meta and para substituted benzene ring at the nitrogen atom were synthesized via Paal-Knorr condensation of 1,4-di(2-thienyl)-1,4-butanedione with corresponding halo-substituted anilines. The mon...
Synthesis of Magnetic Fe3O4-Chitosan Nanoparticles by Ionic Gelation and Their Dye Removal Ability
ŞAHBAZ, DENİZ AKIN; YAKAR, ARZU; Gündüz, Ufuk (2015-05-01)
The aim of this study was to synthesize magnetic Fe3O4 chitosan nanoparticles (m-Fe3O4-CNs) by ionic gelation method and use them as adsorbent for the removal of Bromothymol Blue (BB) from aqueous solutions. Also, the effect of various parameters on the preparation of m-Fe3O4-CNs was investigated in this study. The nanoparticles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), dynamic light scattering (DLS), Fourier transform infrared (FTIR) spectroscopy and ...
Synthesis and characterization of polythiophene/montmorillonite and polythiophene/polypropylene composites
Dülgerbaki, Çiğdem; Küçükyavuz, Zuhal; Department of Chemistry (2006)
In this study, polythiophene(PTP)/montmorillonite(MMT) nanocomposites were synthesized by in situ intercalative polymerization and chemical oxidative polymerization. In in situ intercalative polymerization method, composites containing 90 and 95% MMT were prepared. In chemical oxidative polymerization method, a series of composites ranging from 1 to 15% by weight MMT were synthesized. Thermal and morphological properties of samples were investigated by Differential Scanning Calorimeter (DSC), Thermal Gravim...
Synthesis and characterization of conducting copolymers of succinic acid bis-(4-pyrrol-1-yl-phenyl) ester and their electrochromic properties
Ertas, M; Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-05-07)
A new dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and butanedioyl dichloride. Electrochemical behavior of this monomer, succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) was studied. Homopolymerization was achieved by chemical and constant Current electrolysis methods. Copolymerization of SM with thiophene was performed by constant potential electrolysis in acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) and dichloromethane (DCM)-TBAFB, solvent-electroly...
Synthesis of chiral acetoxy lactones via the Baeyer-Villiger oxidation of cyclic aromatic acetoxy ketones
Demir, Ayhan Sıtkı; Aybey, Asuman (Elsevier BV, 2008-12-01)
The alpha-acetoxylation of indanones and tetralones by using Mn(OAc)(3) followed by the enzyme catalyzed kinetic resolution of acetoxy ketones furnished both of the enantiomers of alpha-acetoxy ketones in good chemical and optical yields. The Baeyer-Villiger oxidation of alpha-acetoxy ketones with m-CPBA, CF(3)SO(3)H, and CH(2)O(2), at rt gives the corresponding lactones without racemization. The acetoxy ketone moiety migrates selectively in order to form lactones. The mild hydrolysis of lactones affords ph...
