The rate of reaction was found to be of first order dependence on PCC, N-Acetyl-DL-Methionine, and H<sup>+</sup> ion Concentration. Michaelis–Menten type kinetics is observed respect to substrate. The increase in the rate of reaction with increase in acidity indicates the involvement of a protonated chromium(VI) species in the rate-determining step.

Supercritical water oxidation (SCWO) is an advanced process mainly employed for the treatment of hazardous stable wastes, otherwise treatable by incineration. It is based on the unique properties of water above its critical point ( T c =675 K, P c =22.2 MPa), making it a superior reaction medium for the destruction of all organics in the presence of oxygen. This work presents preliminary laboratory scale studies on SCWO of nitrogen (N)-containing hazardous hydrocarbons, with a view to enhancing the process performance, using available reagents and non-complex reactor design.

The reactions of a series of methyl para-substituted phenylpropiolates 1a–e with piperidine, morpholine, and diethylamine in methanol and dimethylformamide (DMF) have been studied and their rates measured.

The ρ values in methanol ranged between 0.34 and 1.24 whereas in DMF they were between 0.85 and 1.88. The values of ΔS≠ favor a bimolecular rate-limiting step mechanism.

The complex [ Ru(capten)]2+ ( capten = 1-methyl-3,13,16-trithia-6,10,19-triazabicyclo[6.6.6]- icosane ) has been synthesized from [ Ru ( dmf )6]2+ ( dmf = N,N- dimethylformamide ) and the free ligand . An X-ray crystallographic analysis of [ Ru ( capten )] (CF3SO3)2 at 138 K reveals a lel3 conformation of the ligand with an average II-N bond length of 2.136(5) � and an average RuII-S bond length of 2.284(8) � . Visible spectra and the redox potential (1.26 V v. n.h.e .) show that the RuII state is stabilized by c. 0.9 V relative to the complex with six nitrogen donor atoms. Oxidation of Ru11 t

Abstract:

The Kinetics of Oxidative transformation of Methionine by pyridinium chlorochromate in aqueous DMF medium, containing perchloric acid has been studied. The rate of reaction was found to be of first order dependence on PCC, Methionine, and H+ ion Concentration. Michaelis–Menten type kinetics is observed respect to substrate. The increase in the rate of reaction with increase in acidity indicates the involvement of a protonated chromium(VI) species in the rate-determining step. The product of oxidation has been identified as methionine sulfoxide. The rate of reaction increased with increase in d

Abstract:

The electron transfer rate constants in the reduction of Ti4+ and oxidation of Ti3+ in water and in water DMF and water DMSO mixtures were determined by square-wave polarography and by analysis of the DC and pulse polarographic curves. The two reactions occur at different potentials due to the rapid consecutive transformation of the primary product of the electrode reaction. Thus the rate constants are no standard rate constants, and depend on the method employed. The effect of the organic co-solvent varies for both reactions as a consequence of dependence of the degree of electrode coverage o
