The sorption characteristics of epoxy coatings electrodeposited on steel during exposure to different corrosive agents
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Organic protective coatings on steel were formed by cathodic electrodeposition of an epoxy resin modified by an amine and isocyanate using a constant voltage method (resin concentration 10% wt, temperature 26 degrees C, ...
Extraction of cesium from an alkaline leaching solution of spent catalysts using an ion-exchange column
(Marcel Dekker Inc, New York, 1996)
The selective extraction of cesium from an alkaline leaching solution of spent catalysts using phenolic resins was studied. The resins were synthesized by alkaline polycondensation of formaldehyde by phenol, resorcinol, ...
Synthesis and spectroscopic study of some new N-natphthyl substituted 2-phenylacetamides
(Elsevier, Amsterdam, 1990)
In a continuation of our previous works the conformations of new N-(1,2,3,4-tetrahydro-1-napthyl and 1,2,3,4-tetrahydro-2-napthyl) substituted 2-phenylacetamides, PhCH2CONHR, were investigated by vibrational, 1H n.m.r. and ...
Electron‐ionization‐Induced fragmentation of N‐monosubstituted 2‐phenylacetamides
(Wiley, Hoboken, 1990)
Electron‐ionization‐induced mass spectra of N‐monosubstituted 2‐phenylacetamides were recorded and their fragmentation patterns were studied by metastable‐ion analyses. Representative deuterated analogues of these compounds ...
Diureas as ligands in asymmetric reduction of ketones

Preparation of thermoplastic starch
(Serbian Chemical Society, Belgrade, 1997)
Native starch and WX-starch, i.e., native starch enriched with amylopectin, were mixed with plasticizers and thermomechanically treated in a twin screw mixer in order to obtain thermoplastic starch. Ethylene glycol, propane ...
The flow of Newtonian and drag-reducing fluids around sphere
(Serbian Chemical Society, Belgrade, 1996)
The flow around a sphere placed coaxially in a cylindrical tube, the separation of the boundary layer and the wake shedding phenomena are investigated. The results of the simultaneous determination of the drag coefficients ...
Condensation of 1,3-diketones with cyanoacetamide: 4,6-disubstituted-3-cyano-2-pyridones
(Serbian Chemical Society, Belgrade, 1998)
Elimination of vanadium and arsenic from VKCs catalysts
(Marcel Dekker Inc, New York, 1997)
Vanadium and arsenic eliminations from an alkaline leaching solution of spent VKCs catalysts were studied. To this end, several commercial resins or polymers synthesized in the laboratory were evaluated in a solid-liquid ...
