The thermal decomposition of [Co(NH3)5Cl]Cl2 was studied under non-isothermal conditions, in dynamic air and argon atmospheres. The kinetics of the particular stages of [Co(NH3)5Cl]Cl2 thermal decomposition were evaluated from the dynamic weight loss data by means of the modified Coats-Redfern method. TheD n andR n models were selected as the models best fitting the experimental TG curves. These models suggest that the kinetics and macromechanism of [Co(NH3)5Cl]Cl2 decomposition can be governed by diffusive and/or phase boundary processes. The values of the activation energy,E a, and the pre-exponencial factor,A, of the particular stages of the thermal decomposition were calculated. 相似文献

According to the results of powder X-ray diffraction study of the complex salts of composition [M(NH3)5Cl][M"Cl4] (M = Ir, Rh, or Co and M" = Pt or Pd), the anhydrous salts crystallize in the orthorhombic system (space group Pnma) and are isostructural to the [Ir(NH3)5Cl][PtCl4] complex studied previously. The unit cell parameters of the resulting salts were refined. The metal powders, which were obtained by thermal decomposition of these salts under an atmosphere of hydrogen, were studied by powder X-ray analysis. 相似文献

Preparation and Crystal Structure of (NH4)2[V(NH3)Cl5]. The Crystal Chemistry of the Compounds (NH4)2[V(NH3)Cl5], [Rh(NH3)5Cl]Cl2, and M2VXCl5 with M = K, NH4, Rb, Cs and X ? Cl, O (NH4)2[V(NH3)Cl5] crystallizes like [Rh(NH3)5Cl]Cl2 in the orthorhombic space group Pnma with Z = 4. The compounds are built up by isolated NH4+ or Cl? and complex MX5Y ions. The following distances have been observed: V? N: 213.8, V? Cl: 235.8–239.1, Rh? N: 207.1–208.5, Rh? Cl: 235.5 pm. Both structures differ from the K2PtCl6 type mainly in the ordering of the MX5Y polyhedra. The compounds M2VCl6 and M2VOCl5 with M = K, NH4, Rb, and Cs crystallize with exception of the orthorhombic K2VOCl5 in the K2PtCl6 type. The ordering of the MX5Y polyhedra in the compounds (NH4)2[V(NH3)Cl5], [Rh(NH3)5Cl]Cl2 and K2VOCl5 enables a closer packing. 相似文献

The evolved gaseous analysis (EGA), infrared spectra, and XRD have been applied to the study of solid state reactions of KSCN with five cobalt(II)-ammine complexes: [Co-(NH3)5N3]Cl2. [Co(NH3)5(NO2)]Cl2. [Co(NH3)5(H2O)]Cl3. [Co(NH3)5Cl]Cl2, and [Co(NH3)6]Cl3 in a hydrogen atmosphere. It is found that the existence of KSCN shifts the thermal decomposition of these complexes to a lower temperature. The corresponding peak temperatures are near 140°C. The effect of KSCN is discussed and kinetic parameters of deammine reactions are calculated. 相似文献

Summary Ozone concentrations in ambient air can be determined by measuring light emitted by reaction with the chemiluminescent dye Rhodamine B. The stability of the light emission is increased by protecting the dye by another compound, which reacts with ozone more easily, i.e. gallic acid.The stability of the chemiluminescent surface is also increased by an intermittent sampling procedure. This is accomplished by means of a threeway valve allowing each minute the introduction of ozonized air for about 15 sec in the reaction chamber, followed by the introduction of ozone-free air for about 45 sec. In this way also a check on the stability of the zero-point of the detecting system is obtained.The method is highly selective. No interferences of NO2, Cl2, SO2, H2S, NH3, HCl, H2O2 and HF have been observed at concentrations up to 2 ppm. The sensitivity of the chemiluminescent surface is decreased by adsorbed moisture. The moisture problem can be eliminated by coating the surface with a hydrophobic compound and by controlling the relative humidity of the ozone-free air, introduced into the reaction chamber between the actual ozone measurements.
Ozonanalyse, durch Chemiluminescenzmessung
Zusammenfassung Ozon kann in atmosphÄrischer Luft auf Grund der Chemiluminescenzreaktion mit Rhodamin B bestimmt werden. Dabei wird die StabilitÄt der Lichtemission durch Zusatz von GallussÄure, die leichter mit Ozon reagiert, stabilisiert. Die StabilitÄt der leuchtenden FlÄche wird au\erdem durch ein intermittierendes Probenahmeverfahren verbessert. Hierbei wird je Minute 15 sec lang ozonhaltige Luft und 45 sec lang ozonfreie Luft in die Reaktionskammer geleitet. Dadurch wird zugleich eine Kontrolle des Nullpunktes ermöglicht. Das Verfahren ist sehr selektiv. NO2, Cl2, SO2, H2S, NH3, HCl, H2O2 und HF verursachen bis zu 2 ppm keine Störungen. Da adsorbierte Feuchtigkeit die Empfindlichkeit der leuchtenden FlÄche beeintrÄchtigt, wird diese mit einer hydrophoben Schutzschicht überzogen sowie die relative Feuchtigkeit der ozonfreien Luft, die zwischen den Messungen durch die Kammer geleitet wird, unter Kontrolle gehalten.相似文献

Summary Rate constants are reported for mercury(II)-catalysed aquation of thetrans-[Rh(en)2Cl2]+, [Cr(NH3)5Cl]2+, andcis-[Cr(NH3)4(OH2)Cl]2+ cations in water and in methanol-, ethanol-, and acetonitrile-water solvent mixtures. In the case oftrans-[Rh(en)2Cl2]+, the dependence of rate constants on mercury(II) concentration indicates reaction through a binuclear (Rh-Cl-Hg bridged) intermediate. The dependence of the equilibrium constant for the formation of this intermediate and of its rate constant for dissociation (loss of HgCl+) on solvent composition have been established. With the aid of measured solubilities, published ancillary thermodynamic data, and suitable extrathermodynamic assumptions, the observed reactivity trends for these mercury(II)-catalysed aquations are dissected into initial state and transition state components. The reactivity patterns for these three complexes are compared with those for mercury(II)-catalysed aquation of other chloro-transition metal complexes, particularlycis-[Rh(en)2Cl2]+, [Co(NH3)5Cl]2+, and [ReCl6]2–. 相似文献

The values of the kinetic parametersE andA were determined by Kissinger's method on the basis of the DTA, DTG and DSC curves of particular stages of the thermal decomposition of [Co(NH3)6]2(C2O4)3· 4H2O in air and argon atmospheres. It is shown that the use of Kissinger's method for different kinds of experimental curves (DTA, DSC, DTG) leads to close results.

Argon wurden nach dem Kissinger-Verfahren auf der Basis von DTA-, DTG- und DSC-Kurven Werte für die kinetischen ParameterE undA ermittelt.

DTA and TG studies in air were carried out for hydrothermally prepared rhombohedral double carbonates of dolomite type, CaMg(CO3)2, CaMn(CO3)2, CdMg(CO3)2, CdMn(CO3)2 and CdZn(CO3)2. The solid decomposition products in air have been compared to those obtained under hydrothermal conditions with CO2 pressure. The dolomite [CaMg(CO3)2] decomposes in two stages both in air as well as under high CO2 pressure. The other carbonates studied, follow a single stage decomposition in air and a two stage decomposition under hydrothermal condition. In air, the manganese containing carbonates CaMn(CO3)2 and CdMn(CO3)2, decompose to form mixed oxides of CaMnO3 and CdMnO3 respectively, while CdMg(CO3)2 and CdZn(CO3)2 decompose to their respective two mono oxides.
Zusammenfassung Mittels DTA und TG in Luft werden die hydrothermisch hergestellten rhomboedrischen Doppelkarbonate (Dolomittyp) CaMg(CO3)2, CaMn(CO3)2, CdMg(CO3)2, CdMn(CO3)2 und CdZn(CO3)2 untersucht. Die in Luft erhaltenen festen Zersetzungsprodukte wurden mit denen verglichen, die unter hydrothermischen Bedingungen mit CO2-Druck entstehen. Dolomit zersetzt sich sowohl in Luft als auch unter hohem CO2-Druck in zwei Schritten. Die übrigen untersuchten Karbonate zersetzen sich in Luft in einem, unter hydrothermischen Bedingungen in zwei Schritten. In Luft zersetzen sich die magnesiumhaltigen Karbonate CaMn(CO3)2 und CdMn(CO3)2 unter Bildung der Mischoxide CaMnO3 und CdMnO3, während aus CdMg(CO3)2 und CdZn(CO3)2 jeweils die entsprechenden beiden Monoxide entstehen.相似文献

The hydrothermal and decomposition reactions of differently ground gibbsite and its reaction products were studied. The samples were treated isothermally under hydrothermal conditions or in air, and the products were characterized by thermogravimetry and IR spectroscopy. It was found that the method and duration of grinding and the particle size of the starting gibbsite influenced the reactivity of the gibbsite itself and that of the primary reaction products. In a later step of the reaction sequence (hydrothermal rehydration of-alumina), the effects of the differences in the properties of the starting gibbsites were insignificant.

The thermal decomposition of [Ru(NH3)6]Cl3 leads between 200 and 400° in inert gas to metallic ruthenium through the intermediates [Ru(NH3)5Cl]Cl2, [Ru(NH3)4Cl2]Cl and [Ru(NH3)3Cl3]. In the total decomposition $$[Ru(NH_3 )_6 ]Cl_3 \to Ru + 1/2N_2 + 3NH_3 + HCl + 2NH_4 Cl$$ finely divided ruthenium is obtained above 240°. In oxygen the same intermediates are formed, the final product, however, being the metal and its dioxide. 相似文献

The thermal decomposition of [Co(NH3)5CO3]NO3, [Co(NH3)5NO2](NO3)2 and [Co(NH3)5H2O](NO3)3 complexes was studied by simultaneous TG, DTG, DTA (Derivatograph-C), termogastitrimetry, continuous selective water detection, TG-MS, and XRD methods.Due to the nearly explosive reaction of these complexes the samples were heated in a labyrinth-type crucible after a 10-fold dilution with alumina.Through the quantitative determination of NH3 and H2O it was possible to reveal the subtleness of decomposition of these complexes.Based on the qualitative and quantitative results obtained by the different thermoanalytical techniques used the equations of decomposition are given for both stages of the reactions.
Zusammenfassung Mittels simultaner TG, DTG, DTA (Derivatograph-C), weiterhin mittels Thermogastitrimetrie, kontinuierlicher selektiver Wasserdetektierung, TG-MS und XRD-Verfahren wurde die thermische Zersetzung der Komplexe [Co(NH3)5CO3]NO3, [Co(NH3)5NO3](NO3)2 und [Co(NH3)sH2O](NO3)3 untersucht.Wegen dem beinahe explosiven Verlaufes der Reaktion dieser Komplexe wurden die Proben in einem Labyrinth-Tiegel in zehnfacher Verdünnung mit Aluminiumoxid erhitzt.Mittels der quantitativen Bestimmung von NH3 und H2O war es möglich, die komplizierte Zersetzungsreaktion dieser Komplexe aufzuklären.Ausgehend von den mit Hilfe der verschiedenen thermoanalytischen Verfahren erhaltenen qualitativen und quantitativen Ergebnissen wurden die Zersetzungsgleichungen für beide Reaktionsschritte gegeben.相似文献

Synthesis and Structure of Ammine and Amido Complexes of Iridium The reaction of (NH4)2[IrCl6] with NH4Cl at 300 °C in a sealed glass ampoule yields the iridium(III) ammine complex (NH4)2[Ir(NH3)Cl5], which crystallizes isotypically with K2[Ir(NH3)Cl5] in the orthorhombic space group Pnma with Z = 4, and a = 1350.0(2); b = 1028.5(3); c = 689.6(2) pm. The reaction of (NH4)2[IrCl6] with NH3 at 300 °C, however, gives the already known [Ir(NH3)5Cl]Cl2 beside a small amount of [Ir(NH3)4Cl2]Cl2. In pure form [Ir(NH3)5Cl]Cl2 is obtained by ammonolysis of (NH4)2[Ir(NH3)Cl5] at 300 °C with NH3. [Ir(NH3)4Cl2]Cl2 crystallizes triclinic (P1, Z = 1, a = 660,2(3); b = 680,4(3); c = 711,1(2) pm; α = 103,85(2)°, β = 114,54(3)°, γ = 112,75(2)°). The structure contains Cl– anions and [Ir(NH3)4Cl2]2+ cations with a trans position of the Cl atoms. Upon reaction of [Ir(NH3)5Cl]Cl2 with Cl2 one ammine ligand is eliminated yielding [Ir(NH3)4Cl2]Cl, which is transformed to orthorhombic [Ir(NH3)4(OH2)Cl]Cl2 (Pnma, Z = 4, a = 1335,1(3); b = 1047,9(2); c = 673,4(2) pm) by crystallization from water. In the octahedral complex [Ir(NH3)4(OH2)Cl]2+ the four ammine ligands have an equatorial position, whereas the Cl atom and the aqua ligand are arranged axial. Oxidation of (NH4)2[Ir(NH3)Cl5] with Cl2 at 330 °C affords the tetragonal IrIV complex (NH4)[Ir(NH3)Cl5] (P4nc, Z = 2, a = 702.68(5); c = 912.89(9) pm). Its structure was determined using the powder diagram. Oxidation of (NH4)2[Ir(NH3)Cl5] with Br2 in water, on the other hand, gives (NH4)2[IrBr6] crystallizing in the K2[PtCl6] type. Oxidation of (PPh4)2[Ir(NH3)Cl5] with PhI(OAc)2 in CH2Cl2 affords the IrV amido complex (PPh4)[Ir(NH2)Cl5]. 相似文献

The complex was characterized by elemental analysis, infrared, electronic, e.s.r., magnetic moment measurement and X-ray powder diffraction studies. The thermal decompostion of the complex led to NiO in air at about 338° and in nitrogen at about 720°. The activation energies (E

All octahedral angles are close to 90 and 180°. Both structures were refined to very low R values. Water molecule from trans-[Cr(NH3)4(H2O)Cl]2+ is hydrogen bonded to both ionic chlorides. Cation and two anions form the motive which repeats itself in the crystal. Cations and anions of the second structure are distributed in layers.

The hippurates of Co(II), Ni(II), Cu(II) and Zn(II) were isolated from the solution, their quantitative composition and the way of coordination of metal — ligand were determined and the conditions and products of thermal decomposition during heating in air atmosphere up to 1273 K were studied. The complexes of Ni(II), Cu(II) and Zn(II) heated lose some water molecules and then decompose to MO. The hippurate of Co(II) heated loses some water molecules and then decomposes to CoO with intermediate formation Co3O4.
