Solvent effects on the absorption spectra of potentially pharmacologically active 5-alkyl-5-arylhydantoins: A structure-property relationship study / Uticaj rastvarača na apsorpcione spektre potencijalno farmakološki aktivnih 5-alkil-5-arilhidantoinaproučavanje odnosa strukture i svojstava
(Serbian Chemical Society, Belgrade, 2013)
To obtain insight into the interactions of potential anticonvulsant drugs with their surroundings, two series of 5-methyl-5-aryland 5-ethyl-5--arylhydantoins were synthesized and their absorption spectra were recorded in ...
Effects of solvent and structure on the reactivity of 2-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents / Efekti strukture i rastvarača na reaktivnost 2-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2012)
The rate constants for the reactions of diazodiphenylmethane (DDM) with 2-substituted nicotinic acids in nine aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents were ...
Comparative analyses of the diffusion coefficients from thyme for different extraction processes / Uporedna analiza koeficijenata difuzije za različite procese ekstrakcije iz tamjana
(Serbian Chemical Society, Belgrade, 2012)
This work was aimed at analyzing the kinetics and mass transfer phenomena for different extraction processes from thyme (Thymus vulgaris L.) leaves. Different extraction processes with ethanol were studied, i.e., Soxhlet ...
A study of the antibacterial activity and stability of dyed cotton fabrics modified with different forms of silver / Ispitivanje antibakterijske aktivnosti i stabilnosti obojene pamučne tkanine modifikovane različitim formama srebra
(Serbian Chemical Society, Belgrade, 2012)
This study compares the effect of colloidal silver nanoparticles and the commercial RUCO-BAC AGP agent with silver chloride as the active component on the antibacterial activity of dyed cotton fabrics. Cotton fabrics were ...
Enzymatic synthesis of a vitamin B6 precursor / Enzimska sinteza prekursora vitamina B6
(Serbian Chemical Society, Belgrade, 2013)
3-Cyano-4-(ethoxymethyl)-6-methyl-2-pyridone, an important precursor in the synthesis of vitamin B6, is obtained in the addition reaction between 2-cyanoacetamide and 1-ethoxy-2,4-pentanedione catalyzed by lipase from ...
Zinc removal from wastewater by a complexation-microfiltration process / Uklanjanje cinka iz otpadnih voda kompleksirajuće-mikrofiltracionim procesom
(Serbian Chemical Society, Belgrade, 2012)
Due to its wide industrial applications, zinc has become an important contaminant in aquatic environments since it is a toxic heavy metal and some of its compounds, such as zinc arsenate and zinc cyanide, may be extremely ...
3-(Methylamino)propylamine as a templating agent in the synthesis of phosphate-based inorganic polymers / 3-(Metilamino)propilamin kao strukturni agens u sintezi neorganskih polimera na bazi fosfata
(Serbian Chemical Society, Belgrade, 2013)
3-(Methylamino)propylamine (MPA) was studied as a structure-directing agent (template) in the synthesis of open-framework phosphate-based materials. The influence of temperature, mole ratio of reactants, crystallization ...
Arsenic removal from water using low-cost adsorbents - a comparative study / Pregled savremenih metoda za uklanjanje arsena iz vode
(Serbian Chemical Society, Belgrade, 2011)
Inorganic arsenic removal from water using low-cost adsorbents is presented in this paper. Selective removal of As(III) and As(V) from water was performed with natural materials (zeolite, bentonite, sepiolite, pyrolusite ...
Simple one-pot synthesis of thioureas from amines, carbon disulfide and oxidants in water
(Srpsko hemijsko društvo, Beograd, 2016)
The present study reports a new facile methodology for the synthesis of symmetrical and asymmetrical thioureas by a one-pot reaction of the required amine, carbon disulfide and an oxidant, i.e., hydrogen peroxide, ...
