Thermodynamic properties of p-xylene - chloroethans
The importance of accurate thermodynamic data of pure substances and mixtures in research and industry hardly needs any emphasis. Apart from their utility in process design calculations, such data are useful in theoretical ... -
Studies in dehydrochlorination of 1,1, 2, 2 Tetrachloroethane
Dehydrochlorination of tetrachloroethane is studied both in homogeneous as well as in heterogeneous phases. The feasibility of the reaction has been evaluated from thermodynamic considerations. The reaction is found to ... -
studies on oxidation of anthracene
Anthraquinone is an important dye intermediate. The demand for anthraquinone in India is likely to go up in the next few years, making its manufacture promising. Among the various methods, vapour phase catalytic oxidation ... -
Analysis of breakage and coalescence of drops in agitated liquid-liquid dispersions
Abstract not available -
Thermodynamic properties of toluene chloroethane systems
The thesis embodies experimental data on (i) vapour pressure, (ii) vapour–liquid equilibria, (iii) heats of mixing at 25 and 35°C, and (iv) latent heats of vaporization for the systems toluene and chloroethanes. Vapour–liquid ... -
Studies on dealkylation of alkyl aromatic hydrocarbons Part II- Demithylation of xylene isomers and ethylebezene to benzene
The demand for benzene is increasing. The possibilities of preparing it from substituted benzene by dealkylation are investigated in the present work. From the literature pertaining to dealkylation processes, the vapour?phase ... -
Oxidation of Aromatic hydrocarbons
TITLE: THE OXIDATION OF AROMATIC HYDROCARBONS. The literature on the oxidation of benzene, phenol, p-quinone and maleic anhydride has been reviewed. Various kinetic models have been presented for oxidation of benzene but ... -
Heat and mass transfer studies in solid state fermentations
Solid-state fermentation (SSF) processes have long been employed in the production and preservation of a variety of foods, and in the production of enzymes, organic acids, antibiotics and other microbial products. They are ... -
Studies in gas-solid catalytic reactions : redox kinetics in pore-diffusion regime
Knowledge about the effect of diffusional intrusion on the kinetics of a gas–solid catalytic reaction-very common in process industries-is essential for a better understanding of these reactions in industrial reactors. The ... -
Estimation of thermophysical properties of binary organic solutions- surface tensions
Thermophysical properties present an interesting field of research to understand molecular nature and behaviour. The primary reason is that these properties mirror any change at the molecular level. One such property is ... -
Computational fluid dynamics(CFD): Studies on Centrifugal contactors
Annular centrifugal contactors find application in liquid–liquid extraction processes in various industries such as reprocessing of spent nuclear fuel, hydrometallurgy, petrochemicals, pharmaceuticals, etc. The special ... -
Vapour phase oxidation of p-xylene
The kinetic study on the oxidation of p-xylene has been carried out. The oxidation of p-xylene on the following two catalysts has been studied: (a) tin vanadate (b) ferric molybdate (Boreskov’s composition) Ferric molybdate ... -
Mathematical and Statistical Modeling of Epidemiology of Asymptomatic COVID-19 Infections and Vaccine Design Strategies
A defining feature of the COVID-19 pandemic has been the high prevalence of asymptomatic SARS-CoV-2 infections – laboratory-confirmed cases where individuals never develop symptoms. Accurately estimating the proportion ... -
Oxidation of Sulfur Dioxide with Copper (II) catalyst in aqueous solution and on poly-4-vinylpyridine resin
Air pollution by sulfur dioxide is of great concern due to its harmful effects on environment, human beings, fauna and flora. Thermal power plants and industries employing combustion of carbonaceous fuels are the major ... -
Studies on fluidised-bed electrode
Flowing electrolyte The mass transfer coefficient k between the flowing electrolyte and the outer wall of an annulus in streamline flow varies as … The mass?transfer data obtained in streamline flow in this investigation ... -
Oxidation of ortho-xylene
The thesis embodies the work on the vapour?phase oxidation of o-xylene over sintered and compacted vanadium pentoxide catalyst in a fixed?bed reactor (FBR) and a continuous stirred?tank catalytic reactor (CSTCR). A survey ... -
Chemical process deveoopment for sodium dithionite- a kinetic study of sodium formate process
(1) The kinetics of formation of sodium dithionite has been investigated in homogeneous aqueous phase. The rate of hydrolysis of sodium formate has been found to be the rate?controlling step. The following rate equation ... -
Studies in drop formation
An exhaustive survey of literature has indicated that no investigation has been carried out on drop formation in non?Newtonian fluids. Further, it is noted that little attention has been paid to the problem of drop formation ...
