Published 1972Staff ViewISSN: 1572-8838Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyElectrical Engineering, Measurement and Control TechnologyNotes: Abstract The reduction of nitrobenzene by an electrolytic method is fairly simple and it does not require the complicated equipment needed in the vapour phase reduction method. On account of the simplicity of operation, an attempt is being made to work out a suitable electrolytic method for this tonnage of chemical and study its economics as compared to other known methods of production. In this paper, the results obtained in the preliminary experiments using the rotating electrode technique are discussed. It is found that it is necessary to add certain ‘hydrogen carriers’ to catalyse the reduction. Without the addition of such carriers, complete reduction is not possible. Various conditions such as current density, depolarizer ratio, temperature and concentration of the hydrogen carrier have been studied. An attempt is made to work out the material balance for the nitrobenzene employed.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The forming limit diagram and strain distribution under punch stretching at room temperature of an AI-Ca-Zn (superplastic) alloy have been evaluated. Tensile behaviour up to 200° C is reported. The fracture surfaces have been examined by scanning electron microscopy and the results are analysed to support the failure criterion proposed earlier by Marciniaket al.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The tensile flow behaviour in the range 275 to 550 ° C of an ultra-fine-grained superplastic Al-Ca-Zn alloy is reported. Under certain conditions of temperature and strain rate, superplastic ductility could be established. Fracture surfaces of tensile specimens tested in the above temperature range were examined by scanning electron microscopy and a correlation could be obtained between the ductility, as revealed by the tension tests, and the fracture behaviour. The fractographic studies also suggested a transition in the deformation process from grain deformation (mainly slip) at the lower temperatures to grain-boundary deformation (predominantly grain-boundary sliding) in the vicinity of 425 ° C.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract Bi-2 2 2 3 superconductors with silver additions are synthesized by sol–gel process. The effect of silver on the formation of Bi-2 2 2 3 phase is studied. The addition of silver brings down the reaction temperature as well as annealing time for the formation of Bi-2 2 2 3 phase. The presence of silver affects the Tc of the Bi-2 2 1 2 phase. The heat treatment of silver added Bi-2 2 2 3 samples above 1113 K show poor superconducting properties due to partial melting of Bi-2 2 2 3 phase. © 1998 Chapman & HallType of Medium: Electronic ResourceURL: -

ISSN: 0178-515XSource: Springer Online Journal Archives 1860-2000Topics: Process Engineering, Biotechnology, Nutrition TechnologyNotes: Abstract Biodegradation of resorcinol and catechol was studied in upflow anaerobic fixed film-fixed bed (FFFB) reactors of uniform dimensions in mono and multisubstrate matrices. Cross feeding studies have revealed that phenol was poorly degraded in resorcinol acclimated reactor whereas it was readily degraded in catechol acclimated reactor. Addition of resorcinol along with phenol in a COD ratio 1:3 in resorcinol reactor increased phenol removal efficiency to 95% indicating that resorcinol induces phenol degradation. When both resorcinol and catechol were fed to the resorcinol acclimated reactor, it was observed that resorcinol degradation was inhibited by catechol. Catechol acclimated reactor could degrade phenol readily when added as mono substrate indicating that it may be an intermediate in catechol degradation. In binary mixture studies also catechol reactor could degrade phenol, resorcinol and hydroquinone to 90%. Catechol acclimated reactor exhibits relaxed substrate specificity whereas resorcinol acclimated reactor exhibits rigid substrate specificity for phenol as well as other isomers.Type of Medium: Electronic ResourceURL:
