Boron removal by anion exchangers impregnated with citric and tartaric acids
(Taylor & Francis Inc, Philadelphia, 1996)
The separation of boron compounds, boric acid and borax, with anion-exchange resins, before and after impregnation with citric and tartaric acids, has been studied. Three different commercially available anion exchangers ...
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 ...
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, ...
Diureas as ligands in asymmetric reduction of ketones
(Amer Chemical Soc, Washington, 1996)
Gas-solid and gas-liquid mass-transfer coefficients
(Wiley, Hoboken, 1996)
Analysis of mass transfer in beer dialysis and diafiltration with two different membranes
(Serbian Chemical Society, Belgrade, 1996)
Experimental investigation of selective alcohol removal from beer by dialysis and dialysis with transmembrane pressure (diafiltration), using two different hollow-fiber membranes: Cuprophan (regenerated cellulose) and ...
The time dependence of chitosan nonionic surfactant solution viscosity
(Dr Dietrich Steinkopff Verlag, Berlin 33, 1996)
The measurement of the viscosity of semiconcentrated chitosan (0.08-0.14%) solutions in the system with octaethyleneglycol mono n-dodecylether (C(12)E(8)) was carried out using Cannon-Fenske capillary viscometer. The ...
Synthesis, morphology, and formation mechanism of mullite particles produced by ultrasonic spray pyrolysis
(Cambridge Univ Press, New York, 1996)
Submicrometer spherical particles of mullite powder were synthesized by ultrasonic spray pyrolysis of emulsion and solutions, using tetra-ethyl-orthosilicate (TEOS) or silicic-acid and Al(NO3)(3) . 9H(2)O as initial ...
