A cobalt(II) complex with ethylenediamine inside zeolite A
(Slovenian Chemical Society, 1994)
Reaction of the partially dehydrated cobalt(II)-exchanged zeolite A (Co-A) with ethylenediamine (en) at 130 C in an autoclave yields after 24 h a product (Coen-A) in which entire Co(II) content (tetrahedrally coordinated ...
On the determination of copper in its phthalocyanine complex
(Journal of the Serbian Chemical Society, 1993)
A convenient method for copper analysis in copper phthalocyanine and its ring-substituted derivates has been studied. It is based on the complete destruction of the organic component in the sample by a combination of thermal ...
On the possibility of the direct preparation of the sodium salt of copper phthalocyanine-4-sulfonic acid
(Serbian Chemical Society, 1994)
The reaction of a 1:3 molar mixture of the monosodium salt of 4-sulfophthalic acid and phthalic acod, carried out in the presence of NH4Cl, urea, CuSO4 5H2O, and (NH4)2MoO4, does not yield the mono-substituted derivative, ...
A Study of the Mn, Co and Ni Environment in the As-synthesized and Rehydrated-calcined Aluminophosphate with Chabazite-like Topology
(Croatian Chemical Society, 1999)
Diffuse-reflectance spectroscopy (DRS), X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) methods are applied to an investigation of Mn, Co and Ni local environments in MnAlPO, ...
(31)P NMR investigation of some microporous zincophosphates
(Serbian Chemical Society, 1996)
High field magic-angle spinning (MAS) (31)P-NMR investigations of novel porous zincophosphates and their cobalt-containing derivatives confirm the framework structure of alternating Zn(Co)O4 and PO4 tetrahedra. The MAS NMR ...
On the serrated yielding in AlMg6.5 alloy sheet
(Serbian Chemical Society, Belgrade, 1998)
Room temperature tensile tests were performed on AlMg6.5 alloy sheet, with Initial strain rates of 6.7x10(4) s(1), 6.7x10(-3) s(-1) and 6.7x10(-2) s(-1), after imposing 70% cold rolling reductions, and annealing at 320 ...
Effect of convective mass transfer on beer diafiltration
(Inst Brewing, London, 1997)
The industrial application of dialysis for the de-alcoholization of beer is based on a diafiltration method, because a small positive transmembrane pressure an the beer side of the membrane is necessary to prevent ingress ...
Fluid dynamic studies of a three-phase fluidized bed
(Serbian Chemical Society, Belgrade, 1996)
Three phase flow and mixing in the liquid phase were studied for a draft tube fluidized bed (DTFB) operating in a circulating regime. The DTFB was considered as a system consisting of five interconnected compartiments: the ...
Wool fabric characterisation after enzymatic and chlorinating treatment / Karakterizacija vunenog tekstilnog materijala posle enzimske obrade i obrade hlorovanjem
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 1999)
Properties of wool textile products are partly governed by morphological composition and chemical structure of the surface of wool fibre. Both chemical structure and morphological composition are most frequently changed ...
Determination of multiaxial stress linear dimensional change of textile surfaces / Određivanje promene linearnih dimenzija tekstilnih površina pri multiaksijalnom naprezanju
(Savez inženjera i tehničara tekstilaca Srbije, 1999)
Breaking characteristics of loose woven and knitted fabrics are frequently determined by the ball penetration resistance (bursting) (test). The Yugoslav Standard JUS F.S2.022 does not include the determination of sample ...
