Continuous flow synthesis of some 6-and 1,6-substituted 3-cyano-4-methyl-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2019)
In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to ...
A survey on the characterization and biological activity of isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2020)
The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. ...
Substituent effect on C=O stetching vibrations in N-substituted 2-phenylacetamides
(Serbian Chemical Society, Belgrade, 1997)
The infrared spectra have been recorded for the N-substituted 2-phenylacetamides. The effect of substitutents on the spectral characteristics of the C=O group was investigated. When the electron-releasing substitutents are ...
Mussels as a bio-indicator of the environmental quality of the coastal water of the Boka Kotorska Bay (Montenegro)
(Journal of the Serbian Chemical Society, 2011)
The Mediterranean blue mussel Mytilus galloprovincialis was used as a pollution level indicator in the Boka Kotorska Bay of the southeastern Adriatic on the Montenegrin coast. The ever-increasing urbanization and ...
Benzylation of N-benzyl-2-phenylacetamide
(Serbian Chemical Society, Belgrade, 1999)
N-Benzyl-2-phenylacetamide was used as a model for the study of the alkylation of N-substituted 2-phenylacetamides with benzyl chloride in the presence of powdered KOH. The reactions were carried out in the presence and ...
Synthesis of the new lost foam refractory coatings based on talc
(Journal of the Serbian Chemical Society, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a ...
Heat transfer by liquid convection in particulate fluidized beds / ПРЕНОС ТОПЛОТЕ КОНВЕКТИВНИМ МЕХАНИЗМОМ У ПАРТИКУЛАТИВНО ФЛУИДИЗОВАНОМ СЛОЈУ
(Serbian Chemical Society, 2022)
In this work the theoretical model for heat transfer from a wall to a liquid-solid fluidized bed by liquid convective mechanism has been proposed and developed. The model is based on thickness of boundary layer and film ...
Influence of boron doping on characteristics of glucose-based hydrothermal carbons
(Journal of the Serbian Chemical Society, 2022)
In this study, the influence of boron doping on structural and surface properties of carbon material synthesized by a hydrothermal method was investigated, and the obtained results were compared with the previously published ...
Modeling of methane emissions using the artificial neural network approach
(Srpsko hemijsko društvo, Beograd, 2015)
The aim of this study was to develop a model for forecasting CH4 emissions at the national level, using artificial neural networks (ANN) with broadly available sustainability, economical and industrial indicators as their ...
The effect of organic molecules adsorption on hydrogen absorption in relation to the hydrogen evolution reaction
(Serbian Chemical Society, 2001)
The competitive adsorption of organic molecules (2, 7-naphthalenedisulfonic acid) and adsorbed H is of interest in relation to its influence on H absorption into a Pd-Ni electro-deposited alloy. The experimental results, ...
