Electrochemically Generated Catalyst System With Increased Specificity And Efficiency For Olefin Metathesis
(Elsevier Science Sa, 2003)
A facile route for the electrochemical generation of an olefin metathesis catalyst from methylene chloride solution Of WCl6 was described. It was found that reductive, oxidative and pulse electrolysis produced the same ...
Preconcentration and Determination of Lead, Cadmium and Nickel From Water Samples Using a Polyethylene Glycol Dye Immobilized on Poly(Hydroxyethylmethacrylate) Microspheres
(Japan Soc Analytical Chemistry, 2006)
A simple and sensitive preconcentration analysis-atomic absorption spectrometric procedure is described for the determination of lead, cadmium and nickel. The method is based upon on-line preconcentration of metal ions on ...
Chemical Synthesis Of Thiophene-Pyrrole Copolymer
(Slovensko Kemijsko Drustvo, 2003)
Oligomerization reactions of thiophene and pyrrole monomers and chemical copolymerization of these oligomers were investigated in acetonitrile solutions containing thiophene-HBF4, pyrrole-HBF4 and thiophene-pyrrole-HBF4. ...
Quantum Chemical Studies on The Structures of Some Heterocyclic Azo Disperse Dyes
(Arkat Usa Inc, 2008)
The ground-state geometries, absorption wavelengths, oscillation strengths for a series of some novel hetarylazoindole derivatives were studied with density functional theory (DFT) and time-dependent density functional ...
Spectroscopic And Electrochemical Observation Of Hydrogen-Bonded Imidazole And 2-Aminoimidazole Clusters
(Slovensko Kemijsko Drustvo, 2007)
The electroreductions of imidazole and 2-aminoimidazole were investigated on a Pt electrode in acetonitrile containing tetrabutylammonium tetrafluoroborate with and without the presence of HBF4. The effects of lithium and ...
Crystal Structure Of 3,3-Dichloro-N-P-Methoxyphenyl-4-(2-Phenylstryl)-2-Azetidinone

Adsorption Of Mercury(Ii) Ions By Poly(Hydroxyethylmethacryl Ate) Adsorbents With Thiazolidine Groups
(Multi Science Publ Co Ltd, 2002)
A wide variety of adsorbents has been reported in the literature for heavy metal adsorption. We have recently developed a new polymer system for the removal of contaminant heavy metal ions from aquatic systems. Thus, ...
The Effect Of Hydrogen Bonding On The Electroreduction Behavior Of Aminobenzimidazoles
(Slovensko Kemijsko Drustvo, 2004)
The electroreductions of benzimidazole, 5-aminobenzimidazole, 2-aminobenzimidazole and 4-aminobenzimidazole were investigated on a Pt electrode in acetonitrile containing tetrafluoroborat (TBABF(4)) with and without the ...
