Reactivity of beta-aroylacrylic acids with diazodiphenylmethane
(Serbian Chemical Society, Belgrade, 1998)
The rate constants for 10 trans-substituted beta-aroylacrylic acids in their reaction with diazodiphenylmethane (DDM) were determined in ethanol at 30 degrees C. The intention was to study the transmission of electronic ...
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 ...
Complexes cobalt(II), zinc(II) and copper(II) with some newly synthesized benzimidazole derivatives and their antibacterial activity
(Serbian Chemical Society, Belgrade, 1999)
The preparation and properties of some complexes of cobalt(II), zinc(II) and copper(II) with several newly synthesized benzimidazole derivatives (L) are reported, The complexes, of the general formula [MCl2(L)over dot(2)] ...
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 ...
Immobilization of lipase on a hydrophobic zeolite type Y
(Serbian Chemical Society, Belgrade, 1998)
Lipase from Candida cylindracea was immobilized by adsorption on a hydrophobic zeolite type Y. The maximal amount of bound protein of 8.2 mg g(-1) and an immobilization efficiency of 33% were achieved under optimum conditions. ...
Nondispersive solvent extraction-stripping of phenol in a hollow fiber-in-fiber membrane contactor
(Serbian Chemical Society, Belgrade, 1996)
Phenol extraction from aqueous solution and its simultaneous concentration into caustic stripping solution using a hollow fiber-in-fiber type membrane contactor was investigated. The phenol separation rate using sunflower ...
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 ...
Low temperature processes during the synthesis of lanthanum lead borosilicate glasses
(Serbian Chemical Society, Belgrade, 1997)
Low temperature processes during the synthesis of PbO-B 2 O 3 -SiO 2 -La 2 O 3 glasses were studied by thermal analysis of the batch mixture of glasses and X-ray powder diffraction analysis of samples that crystallized ...
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions
(Serbian Chemical Society, Belgrade, 1997)
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions was studied. The lead leaching rates were measured using an agitated vessel at atmospheric pressure. The effects of the MgCl2 ...
