Isomerization and selectivity calculation of the soybean oil hydrogenation process / Izomerizacija i izračunavanje selektivnosti u procesu hidrogenacije sojinog ulja
(Faculty of Technology, Novi Sad, 2000)
Soybean-oil hydrogenation process has been conducted in an industrial reactor by synthesized NICAT-2000 catalyst and by commercial G-70 catalyst under the same working conditions. Although this reaction includes a series ...
NaY zeolite: A useful catalyst for nitrile hydrolysis
(Molecular Diversity Preservation International, Basel, 2000)
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, ...

(Belgrade : Serbian Chemical Society, 2000)
The aim of this work was the investigation of the biotransformation ability of a
synthetic benzofurane type g-lactone. This workwas basedon the microbiological reactions
of Aspergillus niger, Saccharomyces cerevisiae, ...
Isolation and antimicrobial activity of anthraquinones from some species of the lichen genus Xanthoria / Изоловање и антимикробна активност антрахинона неких врста лишајева рода Xanthoria
(Belgrade : Serbian Chemical Society, 2000)
The isolation of six anthraquinones erythroglaucin, physcion, xanthorin, emodin, fallacinal, teloschistin, from three species of the lichen genus Xanthoria (X.fallax, X.elegans and X.policarpa) is reported. Physcion is the ...
A new heterocyclization product of adhyperforin from Hypericum perforatum (St. John's Wort)
(Molecular Diversity Preservation International, 2000)

(Srpsko hemijsko društvo, Beograd, 2000)
The pKa values for a series of eight p-substituted trans-2,3-epoxy-4-phenyl butanoic acids (p-substituted trans-β-aroylepoxyacrylic acids) have been determined potentiometrically in aqueous media at 25 °C at an ionic ...
Activity of some disiloxanes toward the cation exchange resin-catalyst in the siloxane equilibration reaction / Aктивност дисилоксана према катјонској јоноимењивачкој смоли - катализатору реакције силоксанске еквилибрације
(Belgrade : Serbian Chemical Society, 2000)
The relative activities of four disiloxanes toward the cation exchange resin, which was used as an equilibration catalyst, were determined in such a way that the equilibrium initialy present in an arbitrary chosen equilibrate ...
The crystallization and optical properties of LiNbO3 single crystals / Kristalizacija i optičke osobine monokristala LiNbO3
(Belgrade : Serbian Chemical Society, 2000)
LiNbO3 single crystals were grown by the Czochralski technique in an air
atmosphere. The critical crystal diameter Dc = 1.5 cm and the critical rate of rotation wc
= 35 rpm were calculated from the dynamic of fluids ...
