Glycidyl esters synthesis catalysed by ion-exchange resins
(Serbian Chemical Society, Belgrade, 1996)
Ion-exchange resins not previously used for this purpose were employed to study the synthesis of glycidyl esters. The reaction was carried out both with free acids and their sodium salts. The model reaction was the synthesis ...
Thermal investigation of some chelate Ni(II) complexes
(Serbian Chemical Society, Belgrade, 1999)
Several diamine-nickel(II) complexes have been prepared and the kinetic parameters of their decomposition reactions investigated. The complexes undergo a gradual thermal decomposition. First, water is lost, followed by the ...
Bioreactor cultivation conditions modulate the composition and mechanical properties of tissue-engineered cartilage
(Wiley, Hoboken, 1999)
Cartilaginous constructs have been grown in vitro with use of isolated cells, biodegradable polymer scaffolds, and bioreactors. In the present work, the relationships between the composition and mechanical properties of ...
(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 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, ...
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 ...
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 ...
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, ...
Infrared study of N-H...π hydrogen bonding. N-methylbenzamide - Aromatic donor systems
(Serbian Chemical Society, Belgrade, 1996)
The present paper reports the results of an infrared study in the region of the fundamental NH stratching vibration for six N-methylbenzamide - aromatic donor systems. The thermodynamic properties for 1:1 NMBA - aromatic ...
Alkylation of N-ethyl-2-phenylacetamide with benzyl halides
(Serbian Chemical Society, Belgrade, 1996)
Alkylations of N-ethyl-2-phenylacetamide with benzyl halides (chloride, bromide and iodide) in the presence of powdered KOH were carried out in order to establish the possible reaction products as well as to ascertain ...
