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 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, ...
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 ...
Room temperature deformation behaviour of A1Mg6.5 alloy sheet
(Carl Hanser Verlag, Munich, 1999)
Room temperature tensile test have been performed with initial strain rates of 6.7 x 10(-4) s(-1), 6.7 x 10(-3) s-(1) and 6.7 x 10(-2) s(-1), on AlMg6.5 alloy sheet, after imposing 5% to 70% cold rolling reductions, and ...
The determination of kinetics parameters of the hydrogen evolution on Ti-Ni alloys by ac impedance
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloys electrode has been studied by means of steady-state potentiostatic polarization and ac impedance spectrum measurements. Complex-plane spectrum plots are ...
(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 ...
A novel open-framework sodium zincophosphate with isomorphous cobalt(II) substitution
(Royal Society of Chemistry, 1995)
A novel anionic cobalt-substituted zincophosphate framework with a hexagonal unit cell of composition Na6[Co0.2Zn0.8PO4]6·9H2O is synthesised and its crystal structure determined by single crystal X-ray diffraction.
Formation of AlPO4-15 and CoAPO-15 in the presence of hexamethylenetetramine
(Butterworth-Heinemann, 1990)
Two materials, AIPO4-15 and CoAPO-15, with the same aluminophosphate lattice have been obtained by hydrothermal synthesis in the presence of hexamethylenetetramine (HMTA). Their formation is attributed to the influence of ...
Mass spectrometric investigations of some N‐cycloalkyl and N‐aryl fluoroacetamides
(Wiley, Hoboken, 1995)
The electron‐ionization induced mass spectra of some N‐monosubstituted fluoroacetamides of the general formula FCH2CONHR, in which the substituent R is (C3C7) cycloalkyl, phenyl, 4‐methylphenyl, 4‐carbo‐methoxyphenyl, ...
