A rheological study of behavior of polymer-bitumen blends
(Erdoel Erdgas Kohle/EKEP, 1996)
The influence of the elastomer such as SBS and SBR and their mixtures on the structure and rheological properties of blown bitumen B 65 blends, was studied. The crude oil denoted as SEB (Soviet Export Blend) was used to ...
Diureas as ligands in asymmetric reduction of ketones
(Amer Chemical Soc, Washington, 1996)
Gas-solid and gas-liquid mass-transfer coefficients
(Wiley, Hoboken, 1996)
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 ...
Mass and momentum transfer in packed beds of spherical inert particles
(Serbian Chemical Society, Belgrade, 1996)
Mass transfer coefficients between fluid and immersed sphere in liquid dense and loose packed beds of spherical inert particles have been studied experimentally using column 40 mm in diameter. Mass transfer data were ...
Synthesis and characterization of a new chiral polyurea-based catalyst
(John Wiley & Sons Inc, New York, 1996)
A series of chiral poly(urea)s was synthesized by solution polyaddition. The polymers are characterized by NMR, FTIR, DSC, viscosimetry, and microanalysis. After deposition of the rhodium, the insoluble chiral polymers ...
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, ...
31 P MAS NMR investigation of some microporous zincophosphates
(Serbian Chemical Society, Belgrade, 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)O 4 and PO 4 tetrahedra. The MAS ...
