Poly(dialkoxyethyl itaconate)s-I. Some properties of dimethoxyethyl itaconate and its polymer
(Pergamon-Elsevier Science Ltd, Oxford, 1995)
The preparation of dimethoxyethyl itaconate and its polymerisation are described. Some of the properties of the monomer and polymer were determined with special emphasis on the experimental determination of the solubility ...
Local and overall mixing characteristics of the gas-liquid-solid air-lift reactor
(Amer Chemical Soc, Washington, 1994)
Local and overall mixing characteristics were studied for the gas-liquid-solid reactor operating with an internal draft tube and low-density particles. The experimental reactor had a working volume of 7.6 L, column diameter ...
Thermal shock of ceramic material : Damage resistance parameters and critical flaw size
(Trans Tech Publications Ltd., 1997)
The alumina refractories used in this study included a serias of 12 commertial products (two fireclay and ten high alumina brands ) containing ≈ 45 - 90 % Al2O3. Damage resistance parameters R,, R, and RSt were used in ...
Cubic equation of state models for liquid excess heat capacity calculations. II. Applicability of the PRSV-SR and PRSV-HVOS models to complex binary mixtures
(Serbian Chemical Society, Belgrade, 1998)
Binary liquid excess heat capacities C-p(E) for various kinds of complex binary systems measured by Conti and coworkers are well represented by the PRSV EOS modified van der Waals one fluid mixing rule proposed by ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters, 10 - Synthesis and characterization of alpha,omega-dihydroxyoligo(alkylene maleate)s
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees C, of potassium maleate and 1,4-dibromobutane, ...
Modeling of drawing thin glass sheet from a preform
(Serbian Chemical Society, Belgrade, 1998)
A one-dimensional model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
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 ...
Cubic equation of state models for the liquid excess heat capacity calculations. I. Mixing rules
(Serbian Chemical Society, Belgrade, 1998)
Binary liquid excess heat capacities, c(p)(E), were calculated by the PRSV EOS coupled with the van der Waals one fluid (vdW), the modified van der Waals one fluid (Schwartzentruber-Renon)(SR) and the Orbey-Sandler ...
The potential of piezoelectric sensors for characterization of activated carbon cloth applied in adsorption of phenols from air
(Amer Chemical Soc, Washington, 1998)
Characterisation of activated carbon cloth (ACC) applied for phenols adsorption from the air was performed by a pair of coated piezoelectric quartz crystals as sensors. ACC cloth was impregnated with specific organic ...
Sulphatization of manganese slime from zinc electrolysis with ferrosulphate
(Wiley, Hoboken, 1998)
The kinetics and mechanism of the sulphatization of manganese slime from the zinc electrolysis with Fe(ll) sulphate was studied. The priority of chemical reactions was determined on the basis of the results of thermodynamic ...
