Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination
Oren, EE; Tas, AC (1998-05-06)
Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders. Preparation of the phase-pure PZT powders were achieved, in the presence of urea (CH4N2O), by the chemical powder synthesis route of homogeneous precipitation.
Synthesis and optimization of tempo based polymeric oxidation catalysts
Tosun, Ayşegül; Tanyeli, Cihangir; Department of Chemistry (2002)
ree nitroxyl radicals are popular in alcohol oxidation reactions as catalysts. The most useful ones are TEMPO (2,2,6,6-tetramethylpiperidinoxyl) derivatives. In this thesis, TEMPO based polymeric catalyst systems were synthesized. The most important property of these catalysts are being homogeneous and recyclable systems. In the synthetic strategy, the monomer systems which are needed for polymerization were synthesized from easily available norbornene derivatives via Mukaiyama and DCC coupling reactions. T...
Synthesis of tempo containing chiral polymers for kinetic resolution of secondary alcohols.
Yücel, Ece Ayç; Akdağ, Akın; Department of Chemistry (2020)
Optically pure secondary alcohols are important building blocks for the synthesis of chemicals used in pharmaceutical sciences. Kinetic resolution of secondary alcohols through selective oxidation of one enantiomer to the corresponding ketone is a classical and efficient method to obtain enantiopure alcohols. An oxidative kinetic resolution is achieved by exploiting two enantiomers’ unequal rates of oxidation reaction with a chiral reagent or catalyst. The general approach towards a kinetic resolution via a...
Synthesis and characterization of multi-hollow opaque polymer pigments
Asmaoglu, Serdar; Gündüz, Güngör; MAVİŞ, BORA; Colak, Uner (Wiley, 2016-08-05)
A new generation multihollow opaque polymer pigment was synthesized by suspension polymerization of water-in-oil-in-water emulsion method, where methyl methacrylate and ethylene glycol dimethacrylate monomer mixture was used as oil phase. The effects of surfactant and cosurfactant composition in terms of hydrophilic/lipophilic balance on the stability of the water-in-oil emulsion and the size of water droplets were studied. Low droplet sizes and the optimum stability were obtained with Span 80&Tween 80 surf...
Synthesis and characterization of water-soluble oligosalicylaldehyde-sulfanilic acid and its Cu(II), Co(II), Pb(II) complexes
Turac, Ersen; Surme, Yavuz; Sahmetlioglu, Ertugrul; Varol, Ramazan; NARİN, Ibrahim; Toppare, Levent Kamil (2008-10-05)
This work presents the synthesis and characterization of a new water-soluble oligophenol derivative, 4-(2-hydroxybenzylideneamino)benzenesulfanic acid (OSAL-SA) and its metal complexes. The chemical structure of the water-soluble polymer was characterized by nuclear magnetic resonance (H-1 NMR) and Fourier transform infrared (FTIR) spectroscopies and thermogravimetric analyses (TGAs). Pb(II), Cu(II), Co(II) complexes of the polymer were also synthesized in methanol. Characterizations of water insoluble poly...
