Mass transfer between a fluid and an immersed object in liquid-solid packed and fluidized beds / Prenos mase fluid-uronjeni objekat u pakovanim i fluidizovanim slojevima tečnost-čestice
(Serbian Chemical Society, Belgrade, 2005)
The mass transfer coefficient between fluid and an immersed sphere in liquid packed and fluidized beds of inert spherical particles have been studied experimentally using a column 40 mm in diameter. The mass transfer data ...
A study of substituent effects on the NH bond in alkyl and aryl 4,6-disubstituted-3-cyano-2-pyridones / Korelaciona analiza IR i 1H-NMR spektralnih podataka za NH vezu u alkil i aril 4,6-disupstituisanim 3-cijano-2-piridonima
(Serbian Chemical Society, Belgrade, 2007)
Substituent effects on the IR stretching frequencies and 1H-NMR chemical shifts of the pyridone NH group in 4- and 6-disubstituted alkyl and aryl 3-cyano- 2-pyridones were investigated. The bands most sensitive to substituent ...
Gas chromatographic retention indices for N-substituted amino s-triazines on capillary columns. Part V. Temperature dependence of the retention index / Gasnohromatografski retencioni indeksi n-supstituisanih Amino derivata s-triazina na kapilarnim kolonama. Deo V. Uticaj temperature na retencioni indeks
(Serbian Chemical Society, Belgrade, 2003)
The temperature dependence of the retention index was studied for N-substituted amino s-triazines on DB-1, DB-5 and DB-WAX capillary columns within the temperature range 190–230 ºC. Two linear equations with the column ...
Inverse gas chromatography of chromia, Part I: Zero surface coverage / Inverzna gasna hromatografija hromoksida, Deo I - nulta površinska pokrivenost
(Serbian Chemical Society, Belgrade, 2001)
The surface properties of the solid obtained from colloidal chromia were investigated by inverse gas chromatography (IGC), at zero surface coverage conditions. The solid samples I dried at 423 K and II heated at 1073 K in ...
Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, Belgrade, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
