Effect of reactive organobentonite additives to the some performance properties of rigid polyurethane foam
Erdem, Murat; Ortac, Kübra; Erdem, Bilge; Türk, Hayrettin (Gazi University, Fac Engineering Architecture, 2017)In this study, bentonite was modified with the compounds which have amine and hydroxyl functionality and obtained organobentonites were used as additive for the synthesis of rigid polyurethane foam nanocomposites (SPKN). ... -
Electrochemical Determination of Bisphenol A with Pencil Graphite Electrodes Modified with Co(II), Ni(II), Cu(II) and Fe(II) Phthalocyaninetetrasulfonates
Özcan, Levent; Altuntaş, Muhammet; Buyuksagis, Ayşel; Türk, Hayrettin; Yurdakal, Sedat (Japan Soc Analytical Chemistry, 2016)Pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) metallophthalocyaninetetrasulfonates (MePcTSs) were investigated for an electrochemical determination of bisphenol A (BPA). The electrochemical ... -
Latex supported manganese (III) porphyrin catalysts for oxidations of alkenes by hydrogen peroxide and tert-butyl hydroperoxide in the aqueous medium
Türk, Hayrettin (1996)Cationic polymer latexes were prepared by emulsion copolymerization of vinylbenzyl chloride and divinylbenzene followed by quaternization with trimethylamine and used as catalyst supports for 5,10,15,20-tetrakis(2, ... -
Structural studies of water-soluble beta-brominated manganese porphyrins: Stabilities of MnTDCSPPBr8 and MnTSPPBr8 as homogeneous and supported reagents toward hydrogen peroxide and sodium hypochlorite
Türk, Hayrettin; Berber, Hüseyin (2001)This article describes the structural stabilities of [2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetrakis(2,6-dichloro-3-sulfonatophenyl)porphinato]manganese(III) X (where X = $H_2O$ and/or OH- , depending on pH) (MnTDCSPPBr8 ... -
