The main objective of this study is to improve the performance and cleaning up of diesel engine's exhaust by fumigating known quantity of methanol and methyl ethyl ketone individually using a custom made Electronic fuel injector controlled by a microprocessor. To control the emission from diesel engine and to improve performance, alternate fuel and in-cylinder control techniques are used. The e...

Kinetics of Ru (III) catalyzed oxidation of aliphatic ketones such as acetone, ethyl methyl ketone, diethyl ketone, iso-butylmethyl ketone by N-bromosuccinimide in the presence of Hg(II) acetate have been studied in aqueous acid medium. The order of [N-bromosuccinimide] was found to be zero both in catalyzed as well as uncatalyzed reactions. However, the order of [ketone] changed from unity to ...

Abstract The fine chemical and pharmaceutical industries use large amounts of various organic solvents in their manufacturing processes. By reusing them, production costs can be significantly reduced. If we regenerate waste solvent mixtures, have the opportunity to reuse them process or other Our study illustrates an efficient regeneration using example a four-component mixture. Calculations we...

Propionicacidaemia is an inborn error of organic acid metabolism in which there is a defect in propionyl-CoA carboxylase activity, and a clinical picture of overwhelming illness very early in life which was originally described as ketotic hyperglycinaemia (Childs et al., 1961; Hommes et al., 1968; Hsia et al., 1970). These patients have large amounts of glycine in their blood and urine. They al...

The present study was aimed for the effects of exposure to multiple organic solvent vapors in comparison with single exposure to phenol. It included 20 workers exposed to phenol alone and 32 workers of combined exposure to phenol, benzene, toluene and methyl ethyl ketone. A control group of 30 subjects was also included. The levels of transaminases, total proteins, prothrombin time, bleeding ti...

An novel diffusion reaction model for the determination of both the steady-state and transient-state behavior of biofilters for waste air biotreatment is developed and discussed. The model considers the reactor to comprise finite sections, for each of which transient mass balances are established and solved by digital simulation. The elimination of methyl ethyl ketone (MEK) and methyl isobutyl ...

Levulinic acid (LA), 4-oxo-pentanoic acid, is a new platform chemical with various potential uses. In this paper, catalytic hydrogenation and oxidation of levulinic acid were studied. It was shown from experiments that levulinic acid can be hydrogenated to γ-valerolactone (GVL) over transition metal catalysts and oxidative-decarboxylated to 2-butanone (methyl-ethyl-ketone, MEK) and methyl-vinyl...
