The influence of the hydroxylic solvents on the reaction rates of diazodiphenylmethane with cycloalkylcarboxylic and cycloalkenylcarboxylic acids
(Natl Inst Science Communication, New Delhi, 2004)
The rate constants for the reaction of diazodiphenylmethane with cyclohexylcarboxylic, cyclopentylcarboxylic, cyclohex-3-enylcarboxylic and cyclopent-3-enylcarboxylic acids have been determined in ten alcohols at 30degreesC ...
Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures
(Taylor & Francis Ltd, Abingdon, 2004)
The excess molar volume V data of the binary liquid systems were correlated by the Peng-Robinson-Stryjek-Vera equation of state coupled with two different types of mixing rules: composition dependent van der Waals mixing ...
Water plus esters plus methanol: experimental data, correlation and prediction of surface and interfacial tensions at 303.15 K and atmospheric pressure
(Elsevier, Amsterdam, 2004)
For the ternary system water + ethyl propionate + methanol, and the constituent binaries, the surface tension at 303.15 K and atmospheric pressure was measured over the whole miscible composition range. The liquid interfacial ...
Modeling and predictions of solids dynamic holdup in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2004)
A model based on first principles and free of any semiempirical parameters is presented for trickling solids holdup in gas-flowing solids-fixed bed contactors. A small double-cone cavity is used to characterize the voids ...
Lipase immobilization in a hollow fibre membrane reactor: Kinetics characterization and application for palm oil hydrolysis
(Versita, Warsaw, 2004)
Feasibility of lipase immobilization in a hydrophilic hollow fibre membrane reactor for oil hydrolysis has been demonstrated. A simple immobilization technique was applied resulting in about 155 mg m(-2) of immobilized ...
Photoacoustic study of CO2-laser coincidences with absorption of some organic solvent vapours
(Elsevier, Amsterdam, 2004)
Detection of specific molecules in the atmosphere is motivated by the need for monitoring the emission of industrial pollutants. CO2-laser photoacoustic (PA) spectroscopy was used here to obtain coincidence spectra of the ...
Optical fibers with composite magnetic coating for magnetic field sensing
(Elsevier Science Bv, Amsterdam, 2004)
The investigated system for optical fiber sensor was multi-mode optical fiber with magnetic composite coating. Polymer component of composite coating was poly (ethylene-co-vinyl acetate)-EVA, and the magnetic component was ...
Fatigue damage detection in composite rods using fiber optic intensity based sensors
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
An application of the embedded intensity based fiber optic sensors (FOS) for fatigue damage detection in cantilevered composite rods is presented. During the fatigue test with constant amplitude of oscillations, the ...
Support of laboratory accreditation in Central and Eastern Europe by preliminary assessment
(Springer-Verlag, 2004)
The development of a competent and reliable network of accredited laboratories represents one, among other, important means of removal of technical barriers to trade. The achievement of the goal "tested once-accepted ...
Structural analysis of abrasive composite materials with nonwoven textile matrix
(Elsevier B.V., 2004)
The goal of this research was to design the novel composite material based on nonwoven textile material (NTM) while using the existing production facilities. The chosen product was abrasive composite material with nonwoven ...
