Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 20759-14-2, Name is Ruthenium(III) chloride hydrate, Recommanded Product: 20759-14-2.

Some metal complexes of N,N-dihexyl-N?-benzoylthiourea (DHBT) of the type M(DHBT)n [ M=Ni, Pd, Pt, (n=2), Ru, (n=3)] have been synthesised and studied using DTA and TG. These complexes undergo only the pyrolytic decomposition process. The orders, n, the activation energies, E, the pre-exponential factor, A, and the entropies, DeltaS of the thermal decomposition reactions have been derived from thermogravimetric (TG) and differential thermogravimetric (DTG) curves. The characterisation of the end products of the decomposition was achieved by X-ray diffraction. UV-Vis and IR spectra were used for the investigation of characteristic absorption bands and the structural characterisation of ligand and the metals, respectively. Using the Coats and Redfern and Horowitz and Metzger methods performed kinetic analysis of the thermogravimetric data.

The EPR spectra of CsMgCl3 crystals doped with Gd(III) and Ru(III) contain the resonances from a magnetically coupled Gd(III)-Ru(III) pair.The pair spectrum exhibits the fine structure characteristic of a Gd(III) ion (S=7/2) in an axial lattice site.At 77 K the weak coupling with the Ru(III) ion (S=1/2) splits each resonance into a doublet.The spectrum is well enough resolved to allow a characterization as a function of crystal orientation.A spin Hamiltonian which assumes a simple anisotropic interaction between the two ions is adequate to describe the spectrum (Etap=JzSzSz’+Jxy(SySx’+SySy’); where =+0.0055 cm-1 and =0.020 cm-1).The analysis determines that the principal g values of Gd(III) and Ru(III) have opposite sign (for Gd(III): gz=+1.991 and =1.991; for Ru(III): gz’=-2.35 and =1.62).The magnetic properties of the Gd(III)-Ru(III) dimer are discussed.As a part of this analysis, the spectra of a number of monomeric centers containing Gd(III) and Ru(III) were characterized.The properties of these centers are also discussed.

Epoxidation of cyclohexene, 1-octene and styrene by N-methylmorpholine N-oxide in the presence of catalytic amounts of RuCl3 shows first order dependence each in N-oxide and the catalyst.The order in cyclohexene and 1-octene is variable being zero at high concentrations and one at low concentrations.In the case of styrene the order is fractional at all concentrations.The active oxidant is RuV=O species resulting from the oxidation of RuCl3 by NMO.On the basis of experimental observations a reaction mechanism is proposed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of Cl3Ru, you can also check out more blogs about10049-08-8

The compound NaAlH4 has been proposed as a viable hydrogen storage media capable of supplying hydrogen at moderate temperatures and at rates required for fuel cell applications. A number of researchers have subsequently verified and enhanced the rate of dehydrogenation in this system using combined transition metal catalytic additions along with different methods of their introduction into the NaAlH4 compound. The most potent catalytic addition identified thus far is TiCl3 added through ball milling, however, ZrCl3 and other transition metal chlorides have also been found useful. To this date, the role of the catalysts are still unknown as well as their disposition within the NaAlH4 compound. This investigation has sought to identify the extent catalytic dehydrogenation reaction rate of a number of transition metal additions to NaAlH4 at 120C. Two mol% catalysts were added, primarily as chlorides, in a number of valance states. High energy ball mill attrition of the catalyst and the alanate were made with optimum milling times determined. Comparison of dehydrogenation rates with ion radius has shown an optimum catalyst ion radius ratio to be readily identifiable as being midway between that of Al(III) and Na(I). Cation valance, while an important factor in hydrogen discharge kinetics, was shown not to be the primary contributing factor for catalytic activity.

The formation of ruthenium chloro nitroso complexes upon treatment of Ru(III) and Ru(IV) chloro complexes with sodium nitrite and nitric acid inHCl was studied. At 95-100°C, a NaNO2 : Ru ratio of 4 to 12, and c(HCl) = 1-2 mol/l, the yield of the nitroso chloro complexes is nearly quantitative. The mechanism of nitro-sation of ruthenium complexes is p roposed to involve the reduction of Ru(IV) to Ru(III) by nitrous acid and the reaction of ruthenium(III) complexes with nitrogen(II) oxide.

Ornidazole is an antiparasitic drug having a wide spectrum of activity. Literature survey has revealed that no attention has been paid towards the oxidation of ornidazole with any oxidant from the kinetic and mechanistic view point. Also no one has examined the role of platinum group metal ions as catalysts in the oxidation of this drug. Such studies are of much use in understanding the mechanistic profile of ornidazole in redox reactions and provide an insight into the interaction of metal ions with the substrate in biological systems. For these reasons, the Ru(III)- and Os(VIII)-catalyzed kinetics of oxidation of ornidazole with chloramine-T have been studied in HCl and NaOH media, respectively at 313 K. The oxidation products and kinetic patterns were found to be different in acid and alkaline media. Under comparable experimental conditions, in Ru(III)-catalyzed oxidation the rate law is -d[CAT]/dt = k [CAT]o[ornidazole]ox[H+] -y[Ru(III)]z and it takes the form -d[CAT]/dt = k [CAT]o[ornidazole]ox[OH-] y[Os(VIII)][ArSO2NH2]-z for Os(VIII)-catalyzed reaction, where x, y and z are less than unity. In acid medium, 1-chloro-3-(2-methyl-5-nitroimidazole-1-yl)propan-2-one and in alkaline medium, 1-hydroxy-3-(2-methyl-5-nitroimidazole-1-yl)propan-2-one were characterized as the oxidation products of ornidazole by GC-MS analysis. The reactions were studied at different temperatures and the overall activation parameters have been computed. The solvent isotope effect was studied using D2O. Under identical set of experimental conditions, the kinetics of Ru(III) catalyzed oxidation of ornidazole by CAT in acid medium have been compared with uncatalyzed reactions. The relative rates revealed that the catalyzed reactions are about 5-fold faster whereas in Os(VIII) catalyzed reactions, it is around 9 times. The catalytic constant has been calculated for both the catalysts at different temperatures and activation parameters with respect to each catalyst have been evaluated. The observed experimental results have been explained by plausible mechanisms. Related rate laws have been worked out.
