Apparent energy of activation for hot working of vanadium microalloyed steel
(Serbian Chemical Society, Belgrade, 1996)
Two-stage linear In [sinh(ασca)] vs.1/T plots, based on isothermal continuous and anisothermal multipass torsion curves, indicate the double Q HW behaviour of a V-steel. Above T nr , Q HW is independent of all variables ...
Corrosion behaviour of polyester and fluoropolymer coatings on coil coated stainless steel
(Serbian Chemical Society, Belgrade, 1996)
Coil coated stainless steel is a new material for applications in civil and industrial fields with the purpose of reducing maintenance costs and increasing the service life of the products. The corrosion behaviour of ...
The interfacial stability of magnetically stabilized fluidized beds
(Serbian Chemical Society, Belgrade, 1996)
The study concerns a phenomenon in which the magnetization of ferromagnetic particles stabilizes the state of uniform fluidization in gas-solid, liquid-solid and gas-liquid-solid fluidized beds. Fluidization regimes and ...
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 ...
(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 ...
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 ...
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 ...
