A microwave approach to the synthesis of certain 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2014)
A study of the synthesis of 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones from ethyl 2-cyano-3-(substituted phenyl) acrylates and acetophenone is presented. The 2-pyridones were obtained using conventional as well ...
Two-Stage Fermentation for 2-Ketogluconic Acid Production by Klebsiella pneumoniae
(Korean Soc Microbiology & Biotechnology, Seoul, 2014)
2-Ketogluconic acid production by Klebsiella pneumoniae is a pH-dependent process, strictly proceeding under acidic conditions. Unfortunately, cell growth is inhibited by acidic conditions, resulting in low productivity ...
Structural, spectral and thermal properties of 2-(2-pyridylamino)pyridinium trihydrogen pyromellitate / Структурна, спектрална и термичка својства 2-(2-пиридиламино)пиридиниjум-трихидрогенпиромелитата
(Srpsko hemijsko društvo, 2014)
The title compound, (Hdipya)(H(3)pyr), where Hdipya is protonated 2,2'-dipyridilamine and H(3)pyr is the monoanion of pyromellitic acid (H(4)pyr), was obtained from a reaction mixture containing Zn(II) ions, dipya, Na(4)pyr ...
Preparation, characterization and antimicrobial activity of chitosan microparticles with thyme essential oil / Izrada, karakterizacija i antimikrobna aktivnost hitozanskih mikročestica sa etarskim uljem timijana
(Association of Chemical Engineers of Serbia, 2014)
Development of an available drug delivery system is of great interest considering the therapeutic effects of formulations with violate essential oils, especially assuming the fact that using essential oils as antimicrobial ...
The application of NIR spectroscopy with chemometric analysis for monitoring a powder blending process
(Srpsko hemijsko društvo, Beograd, 2014)
This paper reports the use of near infrared (NIR) spectroscopy as a process analytical technology (PAT) tool for monitoring the metformin (N,N-dimethylimidodicarbonimidic diamide) hydrochloride and poly(vinyl pyrrolidone) ...
Linear Free-Energy Relationships Applied to the C-13 NMR Chemical Shifts in 4-Substituted N-[1-(Pyridine-3-and-4-yl)ethylidene]anilines
(Wiley-Blackwell, Hoboken, 2014)
Two series of 4-substituted N-[1-(pyridine-3- and -4-yl)ethylidene]anilines have been synthesized using different methods of conventional and microwave-assisted synthesis, and linear free-energy relationships have been ...
Electrochemical characterization and determination of carbamazepine as pharmaceutical standard and tablet content on gold electrode / Elektrohemijsko karakterisanje i određivanje karbamazepina kao farmaceutskog standarda i sadržaja tablete na elektrodi od zlata
(Association of Chemical Engineers of Serbia, 2014)
The anodic behaviour of carbamazepine (CBZ), an anticonvulsant drug, has been studied on gold electrode in 0.1 mol dm-3 phosphate buffer of pH 7.0 by using cyclic voltammetry. It has been found that the value of the oxidative ...
Economizer water-wall damages initiated by feedwater impurities
(Savez hemijskih inženjera, Beograd, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Removal of magnesium in spring water using the natural zeolite in a continuous flow system / Uklanjanje magnezijuma iz izvorske vode pomoću prirodnog zeolita u protočnom sistemu
(Association of Chemical Engineers of Serbia, 2014)
The aim of this work is an investigation of the possible application of Serbian natural zeolitic tuff ('Igroš Vidojević' deposit, Brus, Serbia) for improvement of the spring water quality. The concentration of magnesium ...
Solvent and Structure Effects on Electronic Absorption Spectra of the Isomeric Pyridinecarboxylic Acids
(Springer, New York, 2014)
Ultraviolet absorption spectra of three isomeric pyridinecarboxylic acids (picolinic, nicotinic, and isonicotinic acids) were measured in 18 various solvents, in the wavelength range from 200 to 400 nm. In order to analyze ...
