(Indian Institute of Science, 2007-06-04)Agitated dispersions of one liquid in another immiscible liquid are widely used in chemical industry in operations such as liquid-liquid extraction, suspension polymerisation, and blending of polymers. When holdup of the ... -
Kinetics Of Polymerization And Degradation By Non-Conventional Techniques
(Indian Institute of Science, 2007-03-28)Non-conventional techniques for polymerization and depolymerization were investigated. The rates of polymerization were enhanced higher in ultrasonic, supercritical fluids and microwaves. However in these system under ... -
Characterisation and Analysis of a Vibro-fluidised Granular Material
(Indian Institute of Science, 2006-12-12)The present work is concerned with the mathematical modelling of a bed of granular material in a gravitational field vertically fluidised by a vibrating surface. The particles are in rapid motion, and lose energy by inelastic ... -
Studies On Oxidation Of Benzylidene Derivatives
(Indian Institute of Science, 2005-10-05)Perfumery compounds isoeugenol and isosafrole can be oxidized to their aldehydes, vanillin and heliotropin respectively. The aldehydes obtained are very useful and commercially valuable products. Apart from their importance ... -
Modelling Of Precipitation In Reverse Micelles
(Indian Institute of Science, 2005-09-20)Nanoparticles have important applications in ceramics, metal catalysts, semiconductors etc. They are normally required to be of small size (~ nm) and monodisperse. The aim of the present work is to model the formation of ... -
Rate Enhancement Of The Catalytic Hydrogenation Of An Unsaturated Ketone By Ultrasonic Irradiation
(Indian Institute of Science, 2005-08-25)The aim of the work was to develop an understanding of the phenomenon of rate enhancement observed when a heterogeneous catalytic reaction system is irradiated by ultrasound. The system under investigation was the catalytic ... -
Studies On The Application Of Liquid Membranes For The Removal Of Dissolved Metals From Effluents
(Indian Institute of Science, 2005-07-21)Separation of dissolved metals from aqueous solutions using liquid membrane technology is highly advantageous owing to the degree of separation achieved, efficiency and application potential. In the present investigation ... -
