Abstract:

The effect of precursors of Co/γ-Al2O3 catalysts prepared from Co(NO3)2 and (CO)6Co2CC(COOH)2 on the Fischer-Tropsch synthesis (FTS) catalytic performance were investigated. All catalysts were characterised by TGA, BET, pore size distribution analysis and TEM techniques. For Aluminium-supported catalyst, the use of cobalt carbonyl cluster as cobalt precursor resulted in a higher activity and C5+ selectivities compared with the reference catalyst prepared from nitrate at low reaction temperature. The activities can be correlated with the zero valent cobalt metal exist on the support. The chain growth attribute to well dispersed smaller metallic cobalt particles resulted from the partial removal of terminal carbonyls at 150°C.

Abstract:

AbstractReactions of the Collman reagent, Na2[Fe(CO)4]·1.5 dioxane, towards the nitrosyl carbonyls [CoNO(CO)3] and [Fe(NO)2(CO)2] in THF as the solvent at room temperature were investigated. Thereby a quick transfer of one nitrosyl ligand from the nitrosyl carbonyl molecule to the iron carbonyl metalate was observed. The reaction with the cobalt compound afforded in high yields the well-known species [Co(CO)4]− and [FeNO(CO)3]− isolated by addition of two equivalents of [PPN]+Cl− ([PPN]+= bis(triphenylphosphane)iminium cation) and characterized by their known IR spectra, by elemental analysis and their characteristic colors and melting points. In the reaction of the Collman reagent with [Fe(NO)2(CO)2] a clean transformation to the tricarbonylnitrosylferrate(1−) as the only formed product was observed.

Abstract:

The cutting fluid is widely used in cutting process with the cemented carbide tool. This paper studied the influence of some antirusting aggents, such as triethanolamine, tri-sodium phosphate, benzotriazole, sodium carbonate anhydrous, on the cobalt leaching of the cemented carbide tool by soaking test. The test results showed that a cobalt on cememted carbide surface and triethanolamine can produce complex compound into solution that made the cobalt leaching. The cobalt of the cemented carbide with the ion of the tri-Sodium phosphate in a water solution can form the loose deposition which leaded to the cobalt leaching.The benzotriazole and the cobalt can generate complex compound film covering on cemented carbide to effective inhibits the cobalt leaching. The inhibitive effect about the cobalt leaching of the sodium carbonate anhydrous is carried out through cathode reaction. The cobalt leaching of cemented carbide tool is effective inhibited by adding the benzotriazole and the carbonate anhydrous in the water-based cutting fluid.

Abstract:

Spherical CoCO3 powder with a small particle size and high density was successfully prepared using a continuous carbonate liquid precipitation method with a raw material of cobalt chloride solution, a precipitant of NH4HCO3, and without a template. The effects of the concentration of ammonium carbonate, process pH, and feeding rate on the tap density and apparent density of cobalt carbonate were investigated. It was found that the apparent and tap density values of 4.4 µm of cobalt carbonate were 1.27 g/cm3 and 1.86 g/cm3, respectively, when the initial concentration of NH4HCO3 solution was 60 g/L, the pH was 7.15–7.20, and the feeding rate of cobalt chloride was 2 L/h. The anisotropic growth process of the crystal lattice plane of CoCO3 under the aforementioned optimal conditions were studied. The results demonstrated that the crystal grew fastest along the (110) facet orientation, which was the dominant growth surface, determining the final morphology of the primary particles. The scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HR-TEM) results demonstrated that the primary particle morphology of the cobalt carbonate was a nanosheet. The unit cell of cobalt carbonate, of a hexagonal structure in the horizontal direction, grew horizontally along the (110) facet orientation, while 20–35 unit cells of the carbon carbonate were stacked along the c-axis in the thickness direction. Finally, the sheet-shaped particles were agglomerated into dense spherical secondary particles, as presented through the crystal re-crystallization model.

Abstract:

The first examples of cobalt-catalyzed multicomponent couplings of mixed aromatic arylzinc reagents with Michael acceptors and carbonyl compounds or imines is described. The reaction system employs a cobalt(II)-2,2′-bipyridine or a cobalt(II)-1,10-phenanthroline complex as a catalyst for both organozinc generation and subsequent multicomponent assembly by formal Michael addition/aldol coupling or Mannich reaction. This study brings new insights into the synthetic scope and mechanism of the reaction.

A magnetorheological material containing iron alloy particles demonstrates magnetorheological strength dependent upon the elements of the alloy and relative concentration of the alloy elements. Selected iron/cobalt alloys demonstrate improved yield strength over traditional carbonyl iron based MR materials when the iron-cobalt alloy has an iron-cobalt ratio ranging from about 30:70 to 95:5. The iron-nickel alloys which have an iron-nickel ratio ranging from about 90:10 to 99:1 maintains superior strength over iron-nickel alloys outside that range.

Abstract Salicylaldehyde derivatives and related β-hydroxo aldehydes CHO-CR=CR′-OH react with CoMe(PMe3)4 via oxidative substitution to form low-spin d6 complexes mer-CoH(CO-CR=CR-O)(PMe3)3. Reductive elimination of acyl and hydride functions from cis positions at the metal is less favourable than in carbonyl cobalt intermediates through a pronounced stabilization by neutral phosphane σ-donor and dianionic acylenolato chelate ligands. Reactions of the hydride complexes with iodomethane or with protic acids HX afford octahedral molecular complexes mer-CoX(CO-CR=CR′-O)(PMe3)3 (X =I, OAc) and mer-CoX(CO-CR=CR′-O)(PMe3)2 (X = OAc, O-CR′=CR-CHO) without opening of the acylenolato chelate ring.

Abstract:

New type of Co-based catalyst was prepared using (CO)6Co2CC(COOH)2 as precursor supported on γ-Al2O3 support. The effects of pretreatment pressures on the catalysts properties and the F-T synthesis performance were investigated in details. Combined with TEM characterization technology, it was found that under different pretreatment pressures (0 MPa, 1.0 MPa, 2.0 MPa), the structure of carbonyl clusters underwent different changes. Moreover, the aggregation degree of cobalt species depends on the pretreated pressure applied. In addition, the catalytic performance of the cobalt carbonyl catalyst pretreated with different pressures was performed and both CO conversion and C5+ selectivity exhibited the order of Co2/2MPa/Al2O3 > Co2/1MPa/Al2O3 > Co2/0MPa/Al2O3.

Abstract:

High Density Polyethylene (HDPE) is a type of plastic that widely used for packaging because it has good mechanical properties. HDPE is naturally non-biodegradable, and the consequence it will increase plastic waste that will damage the environment. To increase their biodegradability, it is necessary to add an oxo-biodegradation additive in the form of a stearate metal compound. This oxo-biodegradation additive is a chromophore that can absorb UV light. Polyethylene oxo-biodegradation films are prepared by mixing HDPE and cobalt stearate to homogeneous on various compositions. To know the effect of adding cobalt stearate into HDPE has done by photodegradation process. The polyethylene oxo-biodegradation film was given irradiation using UV light in the wavelength range 280-300 nm at room temperature for 10 days. After irradiation, in the ATR spectrum shows an absorption peak at 1712 cm-1 wavenumber indicatied the presence of a carbonyl group with a stronger intensity. The higher concentration of cobalt stearate added in HDPE, increases the peak intensity of carbonyl group. This is due to the increasing number of chromophores from cobalt stearate that can absorb UV light, the faster the breakdown of HDPE chains into small fragments so that HDPE is rapidly degraded in nature.

Abstract:

In order to arrange directionally, multi-wall carbon nanotubes (MWCNTs) are functionalized with ferromagnetic cobalt on the surface via the electroless plating method. The uniform and continuous cobalt coating was received in pH [Formula: see text] 9 at 45[Formula: see text]C for 30[Formula: see text]min. It is found that the hydroxyl and carbonyl groups could be successfully introduced on the surface of raw MWCNTs after treated in boiling nitric acid that would provide the active points for cobalt deposition. The diameters of the cobalt (Co)-coated MWCNTs increase to 20–50[Formula: see text]nm from 8–15[Formula: see text]nm of purified ones. As a result of nanoscale cobalt coating, MWCNTs show strong ferromagnetism at room temperature. The Co-coated MWCNT respond to magnetic field susceptibly in the distilled water and arrange themselves in the direction of the applied magnetic field up to 1[Formula: see text]T. The hysteresis curve results show that the coercivity of Co-MWCNTs is 1285.2 Oe, which is about four times that of cobalt powder itself.

Abstract:

A micellar catalyzed oxidation of pentaamminecobalt(III) complexes of α-amino acids by Mn(III)acetate in acidic medium yielding nearly 100% Co(II) and about 100% carbonyl compounds are ultimate products. The unbound amino acids yield about 100% of carbonyl compound in presence of micelles. The effect of variation of sulphuric acid has been carried. The decrease in UV-Visible absorbance at λ=502 nm for Co(III) complex corresponds to nearly 100% of the initial absorbance. In spite of the stoichiometry of Mn(III) to unbound ligand is 2:1, the ratio of Mn(III) to cobalt(III) complex is 1:1 accounting for about 100% reduction at the cobalt(III) centre. The kinetic and stoichiometric results have been accounted. A suitable mechanism consistent with the experimental findings has been proposed by involving a radical cation intermediate.

Abstract:

The paper reports investigations of the direct recovery of copper and cobalt from sulphate solution after leaching of spent Li-ion cells. Metals of high purity (above 99%) can be selectively obtained if the electrolysis process is carried out at proper pH: 1 for Cu and 4 for Co. During cobalt electrowinning, the oxidation of Co(II) ions and formation of Co(III) compounds on the anode were observed. Lithium ions accumulated mainly in the electrolyte. Application of ammoniacal solution for selective lithium carbonate precipitation in the presence of cobalt ions was not effective due to high temperature of the process and no possible formation of the stable and soluble cobalt-ammonia complexes.

Abstract:

The hydrothermal reduction of cobalt, manganese and lithium nitrates with ethylene glycol was studied in the temperature range 100-270 оС in order to obtain nanostructured spinels. The phase composition, particle sizes of the reaction products, and their morphology studied by using IR spectroscopy, X-ray diffractometry, and scanning electron microscopy. We found that the nature of the reaction product of manganese and cobalt nitrates with ethylene glycol (EG) depends on the reaction temperature, the ratio of metal nitrate: ethylene glycol and reaction time. In excess of the reducing agent at temperatures up to 140 оС, observed the formation of metal oxalates. The main product of hydrothermal reduction of manganese nitrate with ethylene glycol at temperatures of 150 оC and 180 оC is manganese oxide Mn3O4 (Hausmanite). At 200 оС obtained the mixture of manganese oxide (Mn3O4) and carbonate (MnCO3). In accordance with the data of X-ray phase analysis at 220 оС and 240 оС, the only reaction product in both cases is manganese carbonate. It was obtained two types of structures on electron-microscopic images of the non-calcined sample at 200 оC: needle-shaped and spherical clusters. It can be assumed that these structures belong to the phases Mn3O4 (Hausmanite) and manganese carbonate MnCO3, respectively. When reduced cobalt nitrate with ethylene glycol in the temperature range 120-220 оC, gives a main amorphous phase, and on X-ray diffraction patterns are observed weak reflections corresponding to cobalt oxide Co3O4. It was shown that upon calcination (at 750 оС) of the samples during the reduction of the mixture of cobalt and manganese nitrates, was obtained the spinel phase of the composition (Co,Mn)(Co,Mn)2O4. In a similar way were obtained Li2CoMn3O8 and LiCoO2 phases (with average particle sizes of 42 nm and 30 nm), which can be used as cathodes in lithium batteries.

Abstract:

The ore from Jingping contains 0.634% nickel, 0.329% copper, 0.047% cobalt, 30.18% SiO2and 19.72% MgO. In order to obtain satisfying beneficiation results, a lot of tests were taken out before, and this article main focus on roughing flotation conditions. Finally find that when the sodium carbonate dosage is 2000g/t, carboxy-methyl cellulose (CMC) dosage is 200g/t, sodium silicate dosage is 100g/t, the combinational effect can depressing the gangue minerals as well as the slime. The final concentration contains 3.03% nickel, 2.01% copper and 2.40% cobalt, the recovery of the nickel, copper and cobalt is 73.03%, 92.58%, 77.62% respectively.

Abstract:

A study of the Pauson-Khand reaction (PKR) based on Co2(CO)8 and binap has revealed that a key precatalyst is (binap)Co2(CO)6, and that alkynes add to this species to generate isomers that interconvert under typical PKR conditions. A 31P NMR study of (binap)(N-(prop-2-enyl)-N-(prop-2-ynyl)-p-toluenesulfonamide)Co2(CO)4 revealed that heating this species gives rise to an unexpected cobalt hydride species (binap)Co(CO)2H together with (binap)Co2(CO)6. Observation of a PKR reaction by 31P NMR spectroscopy revealed that the hydride species is generated during the course of the reaction.

Abstract:

The cobalt complexes HCo(CO)4 and HCo(CO)3(PR3) were the original industrial catalysts used for the hydroformylation of alkenes through reaction with hydrogen and carbon monoxide to produce aldehydes. More recent and expensive rhodium-phosphine catalysts are hundreds of times more active and operate under considerably lower pressures. Cationic cobalt(II) bisphosphine hydrido-carbonyl catalysts that are far more active than traditional neutral cobalt(I) catalysts and approach rhodium catalysts in activity are reported here. These catalysts have low linear-to-branched (L:B) regioselectivity for simple linear alkenes. However, owing to their high alkene isomerization activity and increased steric effects due to the bisphosphine ligand, they have high L:B selectivities for internal alkenes with alkyl branches. These catalysts exhibit long lifetimes and substantial resistance to degradation reactions.
