Kinetic study of the reaction between sodium chloroacetate and potassium ethylxanthogenate / Kinetička ispitivanja reakcije između natrijum-hloracetata i kalijum-etil-ksantata
(Srpsko hemijsko društvo, Beograd, 2007)
The reaction kinetics of the synthesis of sodium ethyl xanthogeneacetate from potassium ethylxanthogenate and sodium chloroacetate in distilled water as the reaction medium at 25, 30, 35 and 40°C, were investigated. The ...
Normal-phase thin-layer chromatography of some angiotensin converting enzyme (ACE) inhibitors and their metabolites / Normalno-fazna tankoslojna hromatografija nekih ACE inhibitora i njihovih metabolita
(Srpsko hemijsko društvo, Beograd, 2009)
The separation and chromatographic behaviour of five ACE (angiotensin converting enzyme) inhibitors and their four active metabolites were investigated by normal-phase thin-layer chromatography on silica using several mono- ...
Acid-base equilibria of the Zn(II) and Fe(III) complexes with condensation products of 2-acetylpyridine and the dihydrazide of oxalic and malonic acid / Kiselinsko-bazne ravnoteže kompleksa Fe(III) i Zn(II) sa kondenzacionim derivatima 2-acetilpiridina i hidrazida oksalne, odnosno malonske kiseline
(Srpsko hemijsko društvo, Beograd, 2009)
Acid-base equilibria of Zn(II) and Fe(III) complexes with N',N'2-bis- [(1E)-1-(2-pyridyl)ethylidene]ethanedihydrazide (ligand L1) and N',N'2-bis[(1E)- -1-(2-pyridyl)ethylidene]propanedihydrazide (ligand L2), i.e., ...
Spectrophotometric investigation of the uranyl-phenylephrine system / Spektrofotometrijsko ispitivanje uranil-fenilefrin sistema
(Srpsko hemijsko društvo, Beograd, 2007)
Using spectrophotometric methods and pH-metric measurements, it was found that the uranyl ion and phenylephrine form a 1:2 complex in the pH region 2.50-4.25 with two absorption maxima at 314.2 nm and 340.6 nm. The ...
Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Srpsko hemijsko društvo, Beograd, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
Reversed-phase thin-layer chromatography of some angiotensin converting enzyme (ACE) inhibitors and their active metabolites / Reversno-fazna tankoslojna hromatografija nekih inhibitora angiotenzin-konvertujućih enzima (ACE) i njihovih aktivnih metabolita
(Srpsko hemijsko društvo, Beograd, 2006)
The chromatographic behaviour of some ACE inhibitors and their active metabolites was examined under conditions of reversed-phase thin-layer chromatography on RP-18 silica using water-methanol, water-ethanol and water-acetone ...
