All-solid-state PVC membrane Ag+-selective electrodes based on diaza-18-crown-6 compounds
Isildak, I; Yolcu, M; Isildak, O; Demirel, N; Topal, G; Hosgoren, H (Springer Wien, 2004)Two diaza-crown ether compounds were synthesized and evaluated as Ag+-selective carriers in polyvinylchloride (PVC) membrane electrodes of solid-state type. The all-solid-state PVC membrane electrode based on N,N-Dibenzy ... -
Crystal structure of N,N?-bis(dodecyl)diaza-18-crown-6 complexed sodium perchlorate
Ozbey, S; Kendi, E; Hosgoren, H; Togrul, M (Springer, 1998)The crystal structure of a new complex of a diaza-crown ether having two side arms has been determined from X-ray diffraction data. The compound crystallizes in space group P (1) over bar with cell dimensions a = 9.982(1), ... -
Effect of structural modifications of diaza-18-crown-6 on the extractability and selectivity of univalent metal picrates
Ziyadanogullari, B; Topal, G; Erdogan, S; Hamamci, C; Hosgoren, H (Elsevier Science Bv, 2001)The solvent extraction of univalent metal cations with N,N'-dibenzyl-1,4,10,13-tetraoxa-7,16 diaza-2,3,11,12-dibenzocycloocta deca-2,11-diene (L-1), N,N'-didodecyl-1,4,10,13-tetraoxa-7,16-diaza-2,3-benzocylooctadeca-2-ene ... -
Electrical and optical properties of inorganic complexes C36H76N2O9ClNa and C14H12N2O4TeBr2
Aydogdu, Y; Yakuphanoglu, F; Aydogdu, A; Temel, H; Sekerci, M; Hosgoren, H (Editions Scientifiques Medicales Elsevier, 2001)The electrical properties of some inorganic samples were studied as functions of temperature and the results were analyzed. These samples activation energies were calculated from the electrical conductivity measurements. ... -
The solvent extraction of alkali metal picrates with 4,13-N,N?-dibenzyl-4,13-diaza-18-crown-6
Hamamci, C; Hosgoren, H; Erdogan, S (Elsevier Science Bv, 1998)Extraction of alkali metal picrates with N,N'-dibenzyl-18-crown-6 was carried out, with dichloromethane as water-immiscible solvent, as a function [ligand]/[metal cation]. The extractability of metal picrates (Li+, Na+, ... -
Solvent extraction of boron with 1,2-dihydroxy-4-oxadodecane (DHD) in n-amyl alcohol
Hosgoren, H; Tural, S; Kahraman, F; Togrul, M; Karakaplan, M (Marcel Dekker Inc, 1997)In the work presented here, 1,2-dihidroxy-4-oxadodecane (DHD) was synthesized and used for the solvent extraction of boron. DHD was prepared from glycidol and octanol by thermal epoxide ring opening reaction without using ... -
Solvent extraction of La3+ with ethylenediamine-N,N?-ditetradecyl-N,N?-diacetic acid (EDDAT) in dichloromethane
Yurdakoc, M; Hosgoren, H (Scientific Technical Research Council Turkey, 1998)Ethylenediamine-N,N'-ditetradecyl-N,N'-diacetic acid (EDDAT) was synthesized for the solvent extraction of La3+. EDDAT was prepared from ethylenediamine-N,N'-diacetic acid (EDDA) and tetradecyl bromide in a basic ... -
Synthesis of chiral monoaza-15-crown-5 ethers from a chiral amino alcohol and enantiomeric recognition of potassium and sodium salts of amino acids
Togrul, M; Askin, M; Hosgoren, H (Pergamon-Elsevier Science Ltd, 2005)The enantiomeric recognition of chiral monoaza-crown ethers for amino acids as their sodium and potassium salts has been investigated by UV-vis. The highest discrimination was observed for TrpK (D/L = 6.47). The reversed ... -
Synthesis of new lariat cyclicdiamides and their metal complexes
Cakir, U; Karakaplan, M; Temel, H; Hosgoren, H; Erk, C (Kluwer Academic Publ, 1996)Three new lariat dilactam host molecules were prepared by the reaction of triethyleneglycol dicarboxylic acid dichloride with N, N'-disubstituted-4, 7-dioxa-1, 10-diazadecane precursors. The amide nitrogen pivot of such ... -
